About twenty years ago
such notions as “Environmental monitoring”, “Risk assessment”, “Contamination management” and “Risk management” were almost unusual not only in Russian but in
English as well. It was due to the recently developed scientific, technical,
economic and political related
spheres of human activity which rapidly grew during the last 20 years. Mercury was recognized as one of the
most dangerous pollutants only recently by
international medical and environmental institutions. Earlier mercury was
widely used in industry, agriculture, scientific researches and in household
activity. Recognition of “mercury hazard” appeared
due to the several
anthropogenic environmental catastrophes in XX century. The most famous one is
the mercury contamination of

The design statement for
the construction of the Pavlodar Chemical Complex (later it was renamed as PCP,
PO “Khimprom” Pavlodar, JSC “Khimprom”, JSC “PCP”, JSC “Kaustic”) was worked
out in 1962 being based on the following documents: Decree of National Economy
Supreme Committee of Council of Ministers of USSR #286-p /1/ dated November 29,
1963; Decrees of Central Committee of the Communist Party of Soviet Union and
Council of Ministers of USSR #795 dated July
23, 1958; #85-30 dated
January 20, 1960; #846-300 dated September 11, 1961 and also Decree of Council of Ministers of USSR #284 dated April 1, 1961. According to the
design statement the projected capacity was planed as much as 120 thousand tons
of caustic soda /2/, 90 thousand tons of liquid chlorine /1/. The construction of PCP started in 1965 and proceeded till 1992. For these years PCP has been managed by
several directors who ran the production. They are: Ju.B.Yezhov (1965-1968)
A.R.Bakhaev (1968-1973), A.C.Korpiakov (1973-1977), C.C.Berketov (1977-1988),
B.A.Sharov (1988-1997), E.P. Sereniuk (1997-1998), A.G.Siryk (1998-2000).

At that time of planned
soviet economy further development of PCP was restricted by a number of
unfavorable factors such as delay in construction of oil-pipe line
Omsk-Pavlodar-Chimkent-Tchardzhou and POR. The latter was caused by the
construction in neighboring Russian oblast bigger Omsk Oil-Refinery. Other factors were: low quality of the halite material – brine from
Industrial Site #1
consisted of 30 shops where wide range of products and commodities was
manufactured such as caustic soda, chlorine, sodium hypo chloride, ammonium chloride, additives to lubricating oil and
engine oils, floto-reagents, anti-freezes, anti-icer, disinfectants and
bleaching agents, plasticizers for plastic mass production, phenol-formaldehyde
resin, some types of
plastic and plastic goods. These products were delivered to industrial plants
of the whole Soviet Union, including
In 1993 after the
termination of caustic and chlorine production which was the basic production
of PCP only those shops survived that produced household chemical goods and commodity (for example shampoo based on a ginseng
extract) and reagents for ore mining and processing and energy industries. Part of these productions was privatized in 1994 during establishment
of JSC “Khimprom” at that they used their facilities on the condition of rent. 90% of JSC “Khimprom”shares belonged to the state. The most standing idle equipment subject to any value were sold in
order to pay to minimum working staff and to cover the debts. The exception was
the defence equipment which were protected by
Soviet-American non-proliferation treaty dated 1989, ratified later also by the Kazakhstan Government. However
Demercurization works at
the cost of republican budget were resumed by JSC “PCP” only in early 2002. By 2005 the first Phase of
demercurization project was accomplished. In 2006 JSC “PCP” was proclaimed a bankrupt and its
property was put for a bid while the territory where demericurization works
were held was withdrawn from the bid lot and still is a communal property. New
chlor-alkali production (with membrane method) will be revived by JSC “Kaustic”
with private capital. JSC “Kaustik” was established in 2004 based on only
private capital and had purchased the half of the property of PCP industrial
site #1 by the beginning of 2006.
1.2.
Chlor-alkali production. History
/4-8/
Production #3 manufactured chlorine and caustic soda (NaOH) since 1975 till 1993 by
electrolysis method where mercury was used as a cathode. There were 80 electrolyzers (CDM 150-7.3) installed in shop #31 (in 1975 - 72 electrolyzers, in 1984 - additionally 8 electrolyzers, and after full repair in
1986 there were 68 electrolyzers totally). The capacity of production amounted
112700 ton of caustic
soda and 100000 ton of chlorine per year. Raw
materials sources: sodium chloride - from Baskunchak (
Horizontal electrolyzer CDM 150-7.3 made in Germany (with maximal load of 150 kA, cathode
current density of 7.3 kA/m2, length of
2NaCl + 2H2O →
2NaOH + Cl2↑ + H2↑,
was divided into two electrochemical
processes:
in the electrolyzer gaseous chlorine was generated on
graphite anode and sodium amalgam - on mercury cathode
2Na+ + 2Cl-
+ (Hg) → 2Na (Hg) + Cl2↑,
and in the decomposer both aqueous solution of
sodium hydroxide and gaseous hydrogen were generated on the surface of a
graphit extension as a result of interaction of sodium amalgam with water
2Na (Hg) + 2H2O →
(Hg) + 2NaOH + H2↑.
Technologically the
process of sodium hydroxide production looked like a travel of depleted sodium amalgam (with sodium concentration ≤ 0.005%)
from the lower part of
the decomposer upward to the electrolyzer inlet with the help of mercury pump, followed by the saturation of amalgam with sodium
under the current up to concentration 0.45 % during its move along sloping bottom of the electrolyzer, entering 0.45% of sodium amalgam from the electrolyzer in the upper part of decomposer and
the formation of NaOH
in the process of interaction of sodium with desalted water on the graphite
extension at trickling of amalgam down along decomposer with lowering concentration
from 0.45 to 0.005%. NaCl brine flowed forward with amalgam in the electrolyzer
while NaOH solution contra flowed to amalgam in decomposer. Concentration
of NaCl in brine at the electrolyzer inlet was 300-310 g/l, in anolyte
outlet - 265-275 g/l (anolyte contained dissolved 0.3-0.5 g/l chlorine). Alkali
solution concentration at the electrolyzer outlet was 43-46%.
Electrolysis brine was
prepared with anolyte additional saturation in the Shop # 34a where it was stored in two horizontal rubberized tanks of
Solutions temperature in
the electrolyzer reached 80-85оС, and in decomposer – 80-100оС. High temperature caused contamination with mercury of all
electrolysis products and wastes: anolyte NaCl depleted solution, solution of
alkali and hydrogen. Alkali was contaminated with elementary atomic-dispersed
mercury; anolyte, chlorine and exhaust gases contained water dissolved mercuric
chloride; hydrogen and output ventilation gases – gaseous mercury. In the long
period of electrolyzers operation a lot of mercury was sludged with the
formation of amalgam oil which was hand-removed regularly from electrolyzer’s
accumulating pockets. For amalgam cleaning the accumulating pockets were rinsed
with purified water.
Alkali solution was
cooled, separated from mercury and other admixtures by
filtering through frame filters FP-50 and afterwards alkali was passed for either
storage or being poured into tanks. Hydrogen was cooled to 20-25оС immediately above the
decomposer so that the most condensable mercury returned in decomposer.
Afterwards hydrogen was cooled again to 15-20оС with the return of condensed
mercury in electrolyzers, and mercury removal with chlorinated water took
place. Remaining chlorine was absorbed from hydrogen with alkali solution (with
NaOH concentration of 180-240 g/l), then purified hydrogen was rinsed with
water, diluted with nitrogen and emitted into the air. Mercury content in
emitted gases shouldn’t had exceeded 0.01 mg/m3.
In winter period however hydrogen was emitted into air skipping purification
stage. Received
in electrolyzers chlorine-gas with concentration Cl2 ≥ 90% and admixture of H2 gas ≤ 1%
was constantly pumped out in collector so that to maintain vacuum of 5-
Mercury that had been
lost during the electrolyzers operation as a result of leakage and during
repair was washed out with water from the electrolysis shop’s floor into the
floor troughs and further into settling pits of mercury contaminated wastewater
sewerage. Troughs and settling pits were periodically cleaned off using
portable titanium vacuum tank one of connecting pipes of which was connected to
vacuum line and another was connected to rubber hose with the help of which
mercury was collected. Collected mercury returned to the electrolyzers. The
floor of electrolysis shop was covered with special coating which was replaced
several times for all time of its operation.
The plant of mercury
sludge thermal regeneration was launched in 1980 with capacity of 150 m3/year and reached the capacity as much
as 48 m3/year. The plant consisted of 3 induction furnaces of
periodic activity. Each furnace had four cylinder baskets with welded
bottom. Heavily contaminated sludge (4-15%) was mixed manually with
sawdust and limestone in the ratio of 20:1:1 and loaded manually in the
baskets. The baskets were placed in the furnaces with the vacuum rate of 0.2 kgc/cm2. Heating was proceeded by
stages for 14-15 hours till the maximal temperature 550-600оС. For mercury vapor condensation a
vertical heat-exchanger with water casing and heat exchange area of
Wastewater sulfide
treatment was located in the buildings 40, 40a und 40b. This treatment plant
was launched in 1975 simultaneously with chlor-alkali production. Treatment
process consisted of pH correction of mercury bearing wastewater, settling of
primary mercury sludge, mercury oxidizing up to Hg (II) by chlorine followed by
removal of chlorine excess, second correction of pH and Hg (II) precipitation
from solution with the help of sodium sulfide. Poorly soluble mercury sulfide
(II) was settled with iron sulfate as a coagulant with following continuous
settling of mercury sludge. Treated effluents were collected in the tank 40d of
Fig.2. Storage tank
for mercury containing wastewater “40d”
There were some major
technological drawbacks of sulfide method: low rate of mercury sulfide sediment
formation, by-processes of soluble poly-sulfides formation and hardships of
solid phase separation. Therefore mercury concentration in wastewater
discharged from 40d tank in the wastewater storage pond did not meet the
standards very often. Besides Production # 3 discharged illegally wastewater to
the pond Balkyldak avoiding sulfide clean-up very often. It forced the
management of PCP to reconstruct the system of wastewater collection and
treatment. In 1978 sulfide based treatment plant was replaced with the facility
based on the ion-exchange however it was operated not regularly. Achieved capacity
reached 30 m3/hour. Wastewater were
filtered, acidified to pH 1-3 and chlorinated in a chlorinator at active
chlorine concentration of 0.1 – 0.8 g/l in the water for clarified water and up
to 2 g/l concentration for non clarified water. Then chlorinated water was
filtered again, de-chlorinated through adsorber filled with ARV charcoal of
Evaporation ponds –
special engineering testing ponds - were constructed in 1976. Their design
capacity was 200 m3/day or 73000 m3/year
of mercury containing effluents. Evaporation ponds are located
After the completion of
special evaporation ponds construction and mercury sewage systems
re-construction unapproved discharge of mercury contaminated wastewater from
chlor-alkali production into the general PCP’s sewage systems going to the pond
Balkyldak became technologically impossible. Communication between Production
#3 and the whole plant was disconnected. The anion–exchange treatment plant was
connected with the evaporation ponds via above-ground sewage system for mercury
contaminated wastewater – pipes made of titanium.

Actual specific mercury
consumption was as much as 1.589 kg/t, while “scientifically justified norms”
required the consumption of 0.3 kg/t, "technically justified norms" –
0.5 kg/t, and “designed norms” – 0.76 kg/t.
The balance of major
mercury technical losses was following: 0.8% of the losses fell at sludge
accumulated and treated during production process; up to 1.9% - vent emissions,
up to 2.6% - sludge sent to mercury factory, up to 3.9% - atmospheric
emissions with hydrogen, up to 11.8% - wastewater and solid sludge transported
to the ponds for solid and liquid mercury wastes, up to 83.7% - unaccounted
losses. The latter were caused by spills and leakage of metallic mercury and
its not full collection during operation and repair of the electrolyzers.
According to the
messages of the former PCP managers /12-13/ it is evident that in 1990-1993
(last period of chlor-alkali production) about 200000 tons of caustic soda was
produced and more then 175 tons of mercury was utilized. Totally about 2.6% of
used mercury was sent for treatment as sludge /11/, i.e. 33 tons. Former the
plant managers also informed /12-13/, that after chlorine production stoppage
and the following building and equipment dismantling (Shop # 31) about 140 tons
of metallic mercury was either poured out of equipment, collected from floors
or thermally extracted from sludge and sent to a mercury factory. Thus the
total loss of mercury during the whole chlor-alkali production process can be
estimated as high as 1310 tons, 1100 tons of which were unaccounted
losses accumulated in the concrete floor and grounds under the Shop # 31 and
its proximity. Chemically aggressive medium there caused quick deterioration
of the equipment of the chlor-alkali production. Electrolyses shop had a higher
then common accident rate because at the period of chlorine overproduction and
filling of all existing tanks with this gas the electrolyzers were either
de-energized or transferred to a lower current load. This adversely affected
electrolyzers’ technical status.
In 1986 Production #3 of
PCP underwent a scheduled capital repair. In 1988 Program of conversion of
technology based on mercury method which was used at electrolysis plants into
membrane technology was accepted in the
Main infrastructure of
the Production #3 was supposed to be kept as it was. The construction of the

of the plant and its conversion /3/
The Program of chemical
weapons development and stockpiling in the
PCP was one of such
plants which in peace time produced both civilian products and dual-purpose
products (caustic soda, Cl2, AlCl3, PCl3
etc.,) which could be used both for chemical and other kinds of weapon. PCP was
the last of big chemical plants to be constructed and in case of emergency it
can be converted easily into only military production manufacturing mostly
binary nerve agents which were developed in the
Although PCP
manufactured precursor chemicals for chemical weapon agents, it has never
produced chemical weapon. Since the early 1980s the construction of Site #2
went very quickly where since 1990 production of phosphorus trichloride –
initial material for organic synthesis of nerve agents was started. Many
specialists experienced in chemical weapon production were sent to the plant
that time. However the construction of technological lines for weapon
manufacturing was not accomplished. In 1987 the
Site #2 was located at

demercurization of chemical industries in the
In 1981 the chlor-alkali
production at JV “Khimprom”,
There was no any special
demercurization activity there. Mercury was poured out electrolyzers and other
equipment and utilized in new production. Demercurization of the equipment was
conducted by mechanical treatment of metal constructions and their rinsing with
water followed by their sending to metallurgical works for remelting. Concrete
building structures of the electrolysis factory were dismantled for a year and
used by population in private construction. Sludge and debris rich in
mercury was sent to Nikitovskiy Mercury Combine in
In 1987-88 the old
chlor-alkali production was closed down at PO “Kaustik”,
Dismantling of equipment
of the old chlor-alkali production took place under the pressure of local mass
media and NGOs requiring precaution measures to be taken because

Pavlodar Hydrogeological
Expedition – Science and Technology Centre “Technolog” (PHH) being a
sub-contractor of JV Evrohim carried out the following fieldwork in 1989-1990:
32 test and observation boreholes on 8 profiles and also 19 additional
boreholes located beyond these profiles were investigated around the shops #
31. Such amount of boreholes allowed hydro-geological conditions to be
determined which chlor-alkali production left behind after its shutdown as well
as rate of contamination in the west part of industrial site #1, including the
main source of contamination – hall of mercury electrolysis. A half of these
boreholes was drilled through the first aquifers and perched groundwater to the
depth of
102 soil samples were
taken from the depth of 0.25-
Mercury concentration in
water and soil samples was determined with atomic-absorption method in the
laboratories of “Ecohydrokhimgeo” (Almaty) and JV Evrohim.
The main results of
balance and hydrological study of chlor-alkali production of PCP were:
- estimated mass of
mercury lost since 1975 till 1989 during the operation of chlor-alkali
production is 1089 tons including 14 - 63 tons with hydrogen and vent exhausts,
- deposited
in floor and grounds under the electrolysis factory – 813- 866 tons,
- dispersed
in the area adjacent to the Production #3, along the roads, place for storage
of wastes and contaminated equipment - 42-45 tons,
- main hot spot of mercury contamination is located within the territory of
electrolysis shop 31 and has an area of
- area
of mercury contaminated soils in the Site #1 is as much as
- plume of
groundwater mercury contamination spreads from Shop 31 west-northwest direction
up to
- in
two cells (#1, 2) of evaporation ponds there are mercury containing sludge from
anolyte clean up. Mercury there represents sparingly soluble mercury sulfide.
Mercury contents in this sludge ranges from 0.01 to 0.33%. Totally
evaporation ponds accumulated 140 tons of mercury salts;
-
in water of the cell for liquid wastes of the special evaporation
pond – from 1 to 2 tons of dissolved mercury;
- pond
Balkyldak received mercury with wastewater discharge. Average mercury
concentration in the surface water of the pond reaches 0.01 mg/l, that is 20
times higher then MPCw. Taking in account the total volume of
wastewater legally discharged to Balkyldak and mercury concentration in these
wastewater one can estimate the total amount of mercury in water and bottom
sediments. It is equal to 10-15 tons;
- hydrogeological
forecast of the further mercury underground spread from PCP showed the
following rate of mercury movement: in perched groundwater and the first
aquifer - 20-46.7 m/year, in the second aquifer - 12-28 m/year and in the third
one - 46-56 m/year.

Demercurization Design of JV Evrohim /21-25/
The development of the
project was carried out in 1988 – 1995 and coincided with the
Priority program of demercurization
developed by JV Evrohim as a result of the study of 1988-1992 lay in the dismantling
of the most contaminated parts of the Shop 31 - electrolyses hall (80
electrolyzers, other mercury bearing equipment, walls, floor slabs, etc…),
washing the dismantled structures at the place and their sorting out. Metallic
equipment after their treatment with oxidants (sodium hypo chloride, hydrogen
peroxide, potassium permanganate, nitric acid, ferrous trichloride) and water
and had to be utilized as a scrap metal, building structures with less then 1%
of mercury – to be put in the specially constructed landfill (a pit of
Main process of mercury recovery was
expected to be carried out with the use of plants of thermal demercurization of
concrete and mechanical demercurization of ground. At that concrete and ground
after recovery of the most amount of mercury from them also had to be placed to
the new sections of the landfill and filled up with ground-concrete mixture.
Concrete debris from the floor of
the electrolysis hall of 20х30 cm size with mercury concentration of 0.3-0.5% had to be treated in
the vacuum chamber electrical furnace of periodic operation under 700-750оС temperature for 2 hours.
It was planned to cool the air
containing mercury vapor in an air condenser with additional water cooling.
Metallic mercury had to be periodically poured into hermetically sealed
containers while the cooled air to undergo additional treatment with adsorbent

well as the local authorities didn’t accept the proposal to abandon JV Evrohim
design completely. It was suggested that BRGM should develop Feasibility Study
(FS) of their proposal /30/ for its further consideration as an alternative
project to JV Evrohim’s one. BRGM developed the project FS “Demercurization and
elimination of mercury source of contamination in
FS suggested conducting:
-
Collection of
additional data on soil-ground characteristics at the Site #1 and on bottom
sediments in the special evaporation ponds and the pond Balkyldak;
-
assessment of water quality in the river
-
simulation of mercury migration with both
groundwater and surface water as well as with the air which should be done to
assess the risk posed to population;
-
technical and economic assessment of
efficiency of different technologies of cleaning from mercury;
-
technical solutions developments on the site
rehabilitation to be funded by World Bank;
-
temporary encapsulation of concrete floor of
Building 31;
-
thermal treatment of
-
construction of anti-filtration screen – cut-off
wall around Building 31.
FS also suggested
approximate distribution of the loan funds (8.2 million Euros) as follow:
- technology
and equipment purchase and personnel training - 50%,
- data
collection and analyses, risk assessment - 25%,
- demercurization,
rehabilitation works at industrial site and construction of cut-off wall - 25%
.
After the comparison of
JV Evrohim and BRGM proposals /31/ it was evident that BRGM technology does not
drastically differ from JV Evrohim proposal however the cost of BRGM project
was much higher then that of JV Evrohim. For example, the method of mercury
recovery according to BRGM 20 times more expensive than that of JV Evrohim. In
compliance with the BRGM proposal

Demercurization activity in 1998-1999
Due to environmental
emergency situation at PCP the head of oblast administration D. Akhmetov
immediately after approving JV Evrohim design by MNREP in 1995 asked for The
Republican authority to fund the demercurization activity. It was expected that
the funding in 1996 would be provided by the Environmental Fund and national
budget but the Ministry of Finance reject the funding due to the budget deficit
(Letter to the RK Government of 07.03.96 №18-2-3/1644) and suggested using
the debt capital from foreign investors and other stake-holders interested in
production of caustic soda by non mercury method. Committee on Emergency showed
no support to The head of
Decision to allocate
funds from the National budget (246 millions tenge in 1998, 373,4189 million
tenge in 1999, 262,8295 million tenge in 2000, total: 882,2464 million tenge)
/33/ was managed to receive only after the project of demercurization was
separated from the project of construction of new production (Protocol of
meeting at Deputy Prime-Minister № 20-11/9195 of 15.08.1997). A considerable
pressure to take the decision to open the funding for demercurization activity
was rendered by the Russian Federation Government: in
In 1998 five years later
after the production stoppage dismantling of Building 31 (Fig.5-6) and wastes
burial was started. These works were funded from local budget because the
national budget could provide 9.3 million tenge for the first year /33/.
Dismantling of electrolyses shop was scheduled for winter 1998-1999 because

study held regularly since early 80s were initiated by the public being worried
with the high probability of contamination hotspot occurrence which was out of
control, as local authority had no power to control defense industry. This
concern was backed up with significant chlorine emissions from the plant
reaching the residential area.
All those researches had
limited funding and as a rule didn’t covered territories adjacent to the plant
due to the secret regime at the plant. Those researches showed the extent of
mercury contamination of soils in 90s didn’t go beyond limits of the plant
territory whilst surface water contamination was limited with the wastewater
storage pond Balkyldak.

investigated with regards to mercury contamination. Exceeding MPCw for
mercury in the snow melted water was found around the gardening
cooperative “Khimik”. Most likely it was found the south end of the mercury
anomaly located to the north from the investigated area. In 1991-1992 the area
of interest was extended up to the north border of the PCP industrial site, and
besides 45 samples of snow melted water additional 32 samples of soil were
taken down to the depth of 50cm. In the gardens of the north suburb 96 samples
of fruit and vegetables were taken. Exceeding MPCw for mercury was

Investigation of mercury contamination of soil in the
territory of PCP and around it (fig.11-16) has allowed revealing some
large centers of contamination with mercury concentration which was 500 times
more than MPCs for mercury (2.1 mg/kg): four of them were at the territory of
the Industrial Site #1 and came from the electrolysis shop 31, the shop of
production solutions regeneration, tanks for mercury containing wastewater
storage and the building of mercury contaminated wastewater treatment plant;
one of them was on the shore of the pond Balkyldak and was connected with
special ponds for storage of mercury wastes.

The location of one of two (the western one) less
intensive hearths of topsoil contamination between the Industrial Site #1 and
the special ponds has overlapped a contour of spread of plume of mercury
contaminated groundwater and, probably, was caused by their reach of a surface
at the cost of evaporation and capillary effects. Second hearth (eastern),
probably, was formed by leaking mercury containing wastewater from the sewerage
system and their accumulation within this area. This assumption was proved by
numerous detection of high concentration of mercury in the borehole 7Р (4250

Surface water in the special ponds being accumulated
because of atmospheric precipitation was contaminated with mercury up to a
level of 50 mg/l (100000 MPCw), in pits to the south from the
special ponds - from 3 to 30 µg/l (6-60 MPCw), in the drain going
along the motorway in the direction to western dam of the pond Balkyldak - from
2 to 18 µg/l (4-36 MPCw), in the pond Balkyldak near the special
ponds - from 3.5 µg/l (7 MPCw) up to 100-300 ng/l (0.2-0.6 MPCw)
in shoaling water along the rest of the coast. The mercury contents in water of
an unfinished emergency canal extended from the pond Balkyldak to the Irtysh
River was not more than 10 ng/l (0.02 MPCw), in floodplain lakes of
the Irtysh River near the villages Pavlodarskoe and Shauke - not more than 9
ng/l (0.018 MPCw), in the Irtysh River - was lower than the
detection limit 2 ng/l (0.004 MPCw) of used analytical procedure.
The mercury concentration in the sludge of the special
ponds ranged from 10 mg/kg to 10000 mg/kg (2-2000 MPCs), in bottom sediment

fishes (0.3 mg/kg) in most cases. Concentration of mercury in tissue of
predatory fishes (mainly pike) caught in the
Gramma grass taken near the 6th wastewater pumping station contained
mercury from 1 mg/kg to 2 mg/kg, however, mercury contents in milk, kidneys and
liver of cows pastured in the territory between the Industrial Site #1 and the
pond Balkyldak did not exceed a similar parameter for these products from other
not polluted areas. Two samples of a hair belonged to employees of PCP
contained mercury at the same level as a hair of residents of Almaty.

4.6. Main content of works on simulation
hydro-geological conditions
In 2001-2002 the work of IHH on creating the model involved following
basic stages: (i) schematization of natural conditions, (ii) preparation of
initial data, (iii) creation the model itself and its calibration, (iv) solving prognosis tasks.
At the first stage all collected information was looked through and
analyzed, their comprehensiveness, reliability and consistency were estimated.
The model of process has being chosen. The borders of the model were designed
and their schematization with boundary conditions and also the schematization
of simulated object (the quantity of layers was determined) was carried out,
the requirements to grid approximation of simulated area in horizontal
projection were determined. Created GIS IHH and database were used to analyze
the data. For the modeling process the system GMS 3.1 was acquired; it was
installed into a computer network of IHH, documentation on use of the system
was translated to Russian.
The initial data for modeling were prepared in accordance with the
results of schematization of hydro-geological conditions and peculiarities of
the modeling system GMS 3.1. Maps of hydro-geological parameters were produced
for each layer of the model. Values of dynamic parameters describing processes
on borders of the model (water levels in wastewater storage ponds Balkyldak and
Sarymsak) were calculated for every time step. The preparation of the initial
data was carried out using the GIS and the database.
The prepared initial data were converted to formats used by the modeling
system GMS 3.1. It was calibrated to prove the model is adequate to natural
conditions. In process of calibration the conditions existing for the
undisturbed period (1970) and then for the period since 1970 till July 2001
were reproduced in model. By fitting parameters they achieved coincidence of
solutions obtained in the model, with the facts obtained as a result of field
research during the last years and summer of 2001. When the coincidence
appeared to be satisfactory it was accepted that the model adequately described
hydro-geological conditions and could be used for forecasting their change. For
the production and calibration of the model the program
4.7.
There were solved both inverse stationary and inverse non-stationary
problem. The stationary problem which was being solved,
represented the year 1970. During solving the non-stationary problem the period
since 1970 till the middle of 2001 was reproduced in the model. An average
error of the solution of the inverse stationary problem was about

Three variants of the prognosis were made in the model:
- the first variant allowed for keeping two
sources of mercury contamination of groundwater (under the shop 31 and in area
of 6th wastewater pumping station), and also that hydro-geological condition
would remain at the same level as in 2001. The prognosis was done for case if
the concentration of mercury in the sources remained constant during all the
prognosis period;
- according to the second variant of the
prognosis the source under the shop 31 was completely isolated with help of
cut-off walls;
- according
to the third variant two sources of mercury (under the shop 31 and in area of
6th wastewater pumping station) remained the same, but however it was simulated
cessation of water delivery from the Irtysh River onto a water treatment plant,
located to the west from the Industrial Site #1 of PCP.
Based on the results of the simulation (the first variant of the
prognosis), it was established that the plume of groundwater polluted with
mercury would spread to the north-northwest direction at the depth from

Mercury contamination levels in the area of the
former electrolysis shop. It is necessary to finish the works projected by
JV Evrohim as soon as possible and connected to encapsulation of the main
hearth of the contamination from an environment. The building 31 should be
demolished and its building structures placed into a landfill. Also
construction of the bentonite cut-off wall reaching down to regional basalt
clay layer should be completed. If the cut-off wall functions in accordance
with the plan and prevents the groundwater containing soluble salts of mercury
from further horizontal spreading there is no necessity to take out and clean
the concrete floor slab of the electrolysis hall of the shop 31, and also
ground under it. The thermal treatment of the construction materials, strongly
contaminated with mercury can be postponed for the future, when mercury price
probably increase and its extraction becomes economically justified. However in
this case it will be necessary to isolate things confined by the cut-off wall,
so that it will become impenetrable for atmospheric precipitation from outside
and mercury vapor from inside that will stop polluting an atmosphere. It will
require construction of specially designed cap (which also should stop
capillary lifting) further to the works which were designed by JV Evrohim’s
design.

Evrohim design /58, 59/
Correction of the
working design of demercurization developed by JV Evrohim in 1995 was
recommended by National Academy of Science of the Republic of Kazakhstan (the
letter of Vise President of NAS RK #481 of 13.05.2003) /60-61/. Necessity of
such correction was caused by the fact that scope of work specified by the
project and accomplished in 1998-1999 prevented substantially the tread of the
It was also found that
the special ponds for liquid and solid mercury wastes were very dangerous
source of an environment contamination by mercury and need to be isolated from
groundwater and ambient air urgently but not after completing first stage of
demercurization works as it was scheduled in the project of 1995. At the same
time it was ascertained that for the period of time passed since 1993 the
buildings of the chlorine and caustic soda production had come to state of
nonoperability and become the source of environment pollution by mercury and
could not be used in productions newly being created. That brought to necessity
to dismantle the building structures and equipment of the shops with their
following demercurization.
Taking into account the
technical characteristics of demercurization objects, their location in the
industrial site and accumulated experience in demercurization activities the
next methods of demercurization were suggested by the correction of the working
design:
- confinement of both hotspots of groundwater mercury
contamination and special evaporation ponds for mercury wastes with help of
cut-off walls,
- excavation of topsoil heavily
contaminated with mercury down to the depth of
- construction
of a cap impermeable for mercury vapors and atmosphere precipitation on the top
of areas confined by the cut-off walls including special evaporation ponds,
- demercurization
of buildings and production structures through their dismantling, cleaning from
sludge and debris followed by burial of the mercury containing wastes in
the special ponds,
- creation
of network of observation boreholes and acquisition of equipment for mercury
monitoring to be done.
These technical
decisions were amendments to the scheme of the whole demercurization project.
They were chosen on the base of experience accumulated at PCP during the
demercurization and lay in following:
5.1. isolation of
hotspots of mercury contamination and the special evaporation ponds from
groundwater impact was carried out by constructing cut-off walls made of
bentonite clays which reached the basalt clay,
5.2. surface
screening on contamination sites was carried out with piling and compacting
bentonite types local clays on the top of the layer of clean soil,
5.3. burial
of demercurization wastes and debris was planned to do at the evaporation ponds
with following the ponds isolation,
5.4. isolation of filled
special evaporation ponds from atmosphere was carried out by creating
multi-layer cap: (i) intermediate leveling layer was consisted of materials
from dismantled dams’ crests, (ii) sorption layer was consisted of ash from the
power plant and served for prevention of capillary rise of water and substances
dissolved in it, (iii) waterproof layer was consisted of bentonite types clay,
(iv) and protection of the cap against rainfalls was provided by the layer of
fertile land with vegetation,
5.5. asphalt
top covering on the landfill for mercury wastes filled up with clay-concrete
mixture was designed for dusting prevention,
5.6. made decision on
demercurization and construction of caps and coverings allow using these areas
in future for constructions on their surface light buildings and structures
without foundations and underground communications network.

Completion of first Phase of chlor-alkali production demercurization program of
2002 – 2004 /62/
In 2002-2004 Building
#31 was dismantled as well as Buildings 34, 34a, 34b (only concrete floors of
these shops were kept) and tanks of Shop # 34b and 6th pumping
station; Buildings 37, 36, 36b, 31d, 109 and water recycling communications
were decontaminated; infrastructure objects including overpasses and rail and
auto ways were either carried to different places or dismantled; cut-off wall
For three years the
works 860 millions tenge were spent, including 295 millions tenge - in 2002,
242 millions tenge – in 2003 and 323 millions tenge - in 2004. Totally since
May 1996 till December 2004 10867.97 thousands tenge were spent in reference
prices of 1991 (about $15 millions) which was 1082.56 millions tenge in
established prices. After the demercurization program completion the
implemented works were approved by State Expert Commission.
State Expert Commission
noticed that grounds for making all technical solutions was the results of the
special high quality studies and the most efficient integrated decisions were
chosen among various possible variants. It was also emphasized that such
decontamination project was the first to be implemented throughout the former
7. Program
of post-demercurization monitoring in Northern industrial area of
7.1.
Development of the Program of post-demercurization monitoring for 2005–2020
/57/
Program of
post-demercurization monitoring in the Northern industrial area of
The main goals of
Program of the mercury monitoring were (i) determination of levels of mercury
content in various environmental objects (atmosphere, soil, surface water and
groundwater) which remained after implementation of the Program of
demercurization of chlor-alkali production at PCP, (ii) control over
these levels changes during 15-year period, and (iii) confirmation of
acceptable level of risk posed from the residual mercury contamination for public
health, including population of northern suburb of Pavlodar and people working
on the territory of PCP.
Field studies and computer simulation carried out in the framework of the
“Toxicmanagement” project in 2001-2002 /55/ have shown that the major risks caused
by mercury contamination in area of PCP were connected with mercury
contamination of groundwater and surface water as well as with evaporation of
mercury on sites of the most intense contamination of soils.
As a result of implementation of the Program of demercurization the risk
caused by pollution of atmosphere by mercury should be completely eliminated.
Entering of mercury to natural water will also be stopped that in turn will
lead to their gradual self-cleaning and reduction of the
risk related to the mercury contamination of groundwater and surface water. One
should expect keeping some level of mercury contamination of soil in area of
PCP however the area of this contamination is not expected to spread further.
Therefore the monitoring of mercury contamination in the area of PCP should
include the following components:
- control over exceeding
of MPCgm for gaseous mercury equal to 300 ng/m3, in near-eath atmospheric layer (
-control over exceeding
of MPCs for total Hg, equal to 2.1 mg/kg
in the soil layer covering mercury landfills;
- control over absence
of spread of mercury pollution in soils with Hg exceeding MPCs for
total Hg equal to 2.1 mg/kg outside of original mercury aureoles (including at
the cost of evaporation of mercury contaminated groundwater) and control
over absence of accumulation of mercury inside of original hotspots of the
mercury contamination;
- control over absence
of spread of groundwater with Hg concentration exceeding MPCw for
dissolved inorganic mercury equal to 500 ng/l toward Pavlodarskoye village and
the Irtysh River;
- observation
over decrease in total Hg concentration in groundwater, including the
groundwater within the mercury pollution plume;
- control over absence
penetration of Hg dissolved into groundwater outside of cut-off wall and
landfills for solid mercury wastes; and observation over level of groundwater
inside of the isolated volumes;
- observation
over levels of total Hg concentration in surface water of the Northern industrial
area of
- observation
over levels of total Hg concentration in fish of wastewater storage pond
Balkyldak.
To achieve these
objectives the following tasks had to be solved:
- determine the
order, periodicity and methods of air, soil and water sampling for their
analysis for total mercury;
- determine the order
and periodicity of other field activities and measurements;
- determine the methods
of chemical analyses for total mercury in samples and order of laboratory
works;
- develop
recommendations on the obtained results interpretation;
- determine resources
needed for the mercury monitoring.
The results of suggested
Program of mercury monitoring should answer the question whether the
demercurization activities of 2001-2004 at the area of PCP were sufficient. In
case of decease in the residual mercury contamination to the level of
acceptable risk the Program of mercury monitoring can be completed in
7.2.
Field study in the Northern industrial area of
In September 2004 AIPET
and PCP undertook a joint field and chemical-analytical studies in the Northern
industrial area of
Comparison of the data
of 2004 (fig. 32) and one received on “Toxicmanagement” project in 2001-2002
showed that as a result of man-caused intervention in hydro-geological
conditions at the area of mercury hotspots in 2003-2004 some local changes in
mercury concentration in groundwater within the contamination plume have
happened.
In some cases when a
borehole happened to locate in the site surrounded by a cut-off wall
concentration of mercury could go up drastically, for example 100 times
increase in mercury concentration was found for the borehole P3. The same
happened for the boreholes located in the site of ruined sewage communications,
for example 10 times increase in mercury concentration was found for the
borehole 87-02, and double one - for borehole B21a. At the same time the
boreholes located in the immediate vicinity to cut-off wall showed decrease in
mercury concentration there, for example, double decrease in mercury
concentration was found for the boreholes 566-00 and 567-00. For the most boreholes
located quite far from the area of demercurization works the change in
concentration level in groundwater did not happen.
Study of new boreholes
drilled in 2003 proved the high level of mercury concentration in groundwater
within earlier found hotspots, especially near the special evaporation ponds.
Besides one more hotspot was found in the site of former mercury sewage system
connecting the industrial site #1 and the special evaporation ponds.
Levels of mercury
concentration in the surface water in the area of demercurization works
increased significantly, including ones in shoaling water along south-west
shore of the wastewater storage pond Balkyldak. It came from the relocation of
great volumes of dust-forming mercury contaminated soil.
Levels of mercury
concentration in soils in the area of demercurization works remained
considerably high, which probably was accounted for non-completed activity at
the moment of sampling. The same places where soils were heavily
contaminated by mercury were the main sources of mercury entering to
atmosphere. Levels of soil mercury contamination outside the mercury hotspots
(for example westward from Central Laboratory) remained
insignificant.
Fig.32 Results of
mercury monitoring campaign in Northern Industrial Area of
It turned out that
in September 2004 it was hard to estimate a long-term impact of the
demercurization works on environment in the area of PCP due to the incompleteness
of this works that time. One can notice local short-term increase in level of
mercury danger in the area of the works caused by dust forming and mercury
emissions from the experimental thermal plant for treatment of mercury
containing construction waste (fig. 22). That increased risk for the workers
involved in demercurization works. The field study of 2004 showed that it
is necessary to expand considerably the scope of further monitoring works
because during demercurization great volumes of mercury contaminated dust
forming soil were relocated which probably could lead to expansion of the
contaminated area.

Project proposal preparation in the framework of International Science and
AIPET, Pavlodar State
University (PSU), IHH, SLM and PCP worked out a project proposal (see Annex D)
the purposes of which were:
- to
identify the risk associated with the spread of groundwater plumes contaminated
with mercury and oil derivates, including their movement through the network of
water intake boreholes in village Pavlodarskoye, and further towards river
Irtysh and/or their rise onto the pastures and, if significant, identify a
management strategy to contain risk;
- to
identify a management strategy for containing the environmental risk, caused by
the mercury pollution of
Project objectives:
· study of the movement of mercury in the
groundwater rise in depressed area in saturated and unsaturated zones and its
accumulation in the shallow ponds and vegetation. Development of management
strategy to contain the risk to population in the vicinity and livestock;
· facilitation of the Laboratory of environmental
protection of PCP with the equipment for
conduction of mercury monitoring, and training
of the local staff;
·
carrying out 3-year
post-containment monitoring program in the Northern industrial area of
Pavlodar, including the monitoring of soils and vegetation of pastures in the
close vicinity of contamination, and development of recommendations for the
further implementation of the monitoring program;
· assessment of possibility for mercury-polluted
groundwater flow to change its direction; study
of interaction of contaminated groundwater with
bearing strata and underlying aquifers;
·
upgrading and detailing
the models of groundwater in the Northern industrial area of
and contamination of groundwater with mercury;

· development and discussion with local
stakeholders the recommendations for the second Phase of demercurization and
other remediation activities in the Northern industrial area of
One of the most
important objectives of the works to be implemented was the creation of
monitoring laboratory PCP capable to carry out the Program of post-demercurization
monitoring in the Northern industrial area of
Project proposal was
discussed in ISTC in October 2004, approved by a collaborator and American
partners, as well as by the Government of the
Experience of
demercurisation works in
- research
activity should start as early as possible desirably while a plant-pollutant
still in operation. This will enable to get an access to archival documents at
the given enterprise and consulting with the specialists and veterans familiar
with details of technological process and its history. Otherwise the most part
of technological and historical information becomes hardly accessible;
- operating enterprises,
even almost bankrupts can provide funding for urgent measures such as
monitoring, risk assessment, development of designs of clean-up, dismantle of
production equipment and buildings, restoration of the territory. These works
in turn can bring additional funding, privileges and assistance in their
activity not related to environmental pollution including their reconstruction,
conversion and provides workers and engineers of those productions with new
employment;
- suppression and hiding
of environmental problems does not bring to their solving, on the contrary it
brings to the crisis increase and sooner or later the problems get out of hand.
At that the problems solution at later stages will cost much higher. Open
discussion of environmental problems and of the course of implementation of
environment protection works attract new partners who come always with new
ideas and frequently with new possibilities for funding. Mass media and public
are very useful tools for solving many difficult tasks of environmental
projects;
- environmental projects are usually very complicated and
require partial execution. After each phase implementation a new monitoring and
risk assessment are required. Such method of the works fulfillment allows
saving substantial financial resources, labor and time;
- the
most difficult and important stage of environmental projects is negotiations,
coordination and approving. Such stages are usually several because achieved
agreements have to be reviewed and corrected in the course of projects’
implementation;
- environmental projects are usually very expensive. It is
important to find and have a few sources of funding. As a rule participation of
ones donors gives opportunity to attract additional funds from other ones.

industrial area of
The Phase I of the
unique project, confining spread of mercury pollution in Pavlodar North
industrial zone is under completion. It limits mercury impact on environment
and population. The project, which was funded at the cost of the Republican
budget, has prevented the mercury contamination of both the
Chlor-alkali production
in Pavlodar Chemical Plant released 1310 tons of metal mercury and mercury
compounds to environment during manufacturing process. This mercury was
accumulated both under the concrete floor of electrolysis shop and surrounding
industrial site and spread with wind from the area of mercury wastes storage
and penetrated into groundwater and went to surface water either. Mercury
evaporation threatened plant employees’ health as well as mercury contaminated
groundwater threatened health of Pavlodarskoye village population where the
groundwater was used as main water resources. With the start of demercurization
activity (April, 1999) hot spring weather caused intensive mercury evaporation
from Shop N31, which was absolutely out of control. As a result of such
evaporation
Similar problems
occurred in other regions of the former

Program
of mercury contamination monitoring for 2005-2020. (Fragments)
1. Concept
Primary sources of
mercury contamination resulted from 18-year operation of chlorine and alkali
production of former PO “Khimprom”,
Field studies and computer simulation carried out within the program
INCO-Copernicus in 2001-2002 have shown that the major risks caused by mercury
contamination in area of former PO "Khimprom" are related to the
contamination of groundwater and surface water as well as to evaporation of
mercury on sites of the most intense contamination of soils.
As a result of implementation of the Demercurization Program the risk
caused by pollution of atmosphere by mercury should be completely eliminated.
Entering of mercury to natural water will also be stopped that will lead to
their gradual self-cleaning and decrease in the
risk related to the mercury contamination of groundwater and surface water. One
should expect keeping some level of mercury contamination of soil in area of
the former PO "Khimprom", Pavlodr, aureole of this contamination,
however, is not expected to spread further.
Therefore the monitoring of mercury contamination in the area of former

Program: ## 1, 2, 3, 4, 5;
3.7.
monitoring of levels of total mercury in
surface water of the Northern industrial area of
3.7.1.
in wastewater storage
pond Balkyldak: 3 sampling points for water on the southern shore near the
former special ponds for mercury wastes, and 1 sampling point on the north-west
corner, 1 sampling point on the north-east corner, 1 sampling point on the
northern shore (6 sampling points in total);
3.7.2. in
unfinished emergency canal Balkyldak-Irtysh: 1 sampling point for water in its
eastern section and 1 sampling point in central section (2 sampling points in
total);
3.7.3. in
ditches located to the South-East from the former special ponds for solid
mercury wastes (2 sampling points);
3.7.4. in
oxbow-lakes located near the villages Pavlodarskoye and Shauke (4 sampling
points);
3.8.
monitoring of the levels of total Hg
concentration in fish from wastewater storage pond Balkyldak is carried out by
analysis of 10 samples of silver crucian carp caught in the south-western part
of the pond.
With the change of
mercury concentration in the air there should be no excess in MPCad
for gaseous mercury equal to 300ng/m³ in any of these sampling sites.
With the change of total
mercury concentration in the soil the results obtained beyond the primary
hotspot should not exceed MPCs equal to 2.1 mg/kg and in the sampling points
within the primary hotspot should not exceed the results obtained during the
previous monitoring stages.
When determining the
total mercury concentration in the groundwater towards north and west beyond
the mercury contamination plume as well as in the surface water of oxbows of
the Irtysh River and not fully constructed emergency discharge canal
Balkyldak-Irtysh the obtained results should not exceed MPCw for dissolved inorganic mercury
equal to 500 ng/l. Within the primary hotspot of groundwater mercury
contamination and for the surface water of the pond Balkyldak and trenches
located south-eastward from the former special ponds for mercury wastes the
obtained results shouldn’t exceed the results of the previous monitoring
stages.
With the change of
mercury concentration in fish tissue inhibiting the pond Balkyldak the obtained
results shouldn’t exceed significantly (10 times and higher) the results of the
previous monitoring stages.
4. Field work and
measurements associated with the
mercury monitoring
When the atmospheric air
is sampled and analyzed for mercury concentration its temperature should be
measured and recorded at the same time. The measurement and recording of wind
speed and direction is also desirable.
When the samples of
surface water and groundwater are taken for subsequent determination of total
Hg concentration, the temperature and pH of the water should be measured and
recorded at the same time. The water levels in observation boreholes and the
water level in the pond Balkyldak should be also measured and recorded during
their sampling. The levels of groundwater in boreholes located inside of the
area isolated by cut-off wall should not exceed the levels in the same
boreholes registered during the previous stages of monitoring.
Fish caught in the pond
Balkyldak should be weighted with the accuracy of ±
5. Frequency
The frequency of the
monitoring is stipulated by the rate of hydro- and geochemical processes in the
site of the former
During the first year of mercury monitoring the
measurements of gaseous mercury should be carried three times per year (spring,
summer and autumn) at the positive values of the air temperature. The same
frequency should be applied for the measurements of mercury in groundwater of
observation boreholes. The measurements of Hg concentration in soils and
surface water should be carried out once a year during summer period.
Providing the
improvement or maintenance of environmental situation related to the risk posed
by mercury contamination, the frequency of all measurements could be reduced to
one time per year for the subsequent four years. In case of deterioration of
the situation the frequency of first year should be kept.
Providing the
improvement of situation the frequency could be reduced to one time in five
years after the initial five-year period monitoring.
10. Expected results
The results of suggested Program of mercury
monitoring should answer the question whether the demercurization activities
carried out in 2001-
11. Justification

There are several
regions in Kazakhstan (Pavlodar and Temirtau) and in the rest of former USSR
(Sterlitamak, Zima, Usolie-Sibirskoye, Bratsk, Volgograd, Kirovo-Chepetsk,
Bereznyaki, Kiev, Sumgait, Begorod, Shvarts), which are contaminated with
mercury as a result of technogenic releases from industrial enterprises (mainly
chlor-alkali productions of PO “Khimprom” and PO “Kaustik” of the former USSR
Ministry of chemical industry, a part of which is still operating). The release
of mercury into the environment has led to significant contamination of surface
and ground water with dissolved mercuric compounds.

population of
The initial Strategy for
the mercury pollution management proposed by JV “Evrohim” (Design of JV
“Evrohim”) [22] assumed that: (i) the equipment would be dismantled,
demercurized and recycled; (ii) the buildings of chlor-alkali production would
be dismantled and the concrete floor of building # 31 together with
contaminated ground from underneath and around of this building would be
excavated and replaced with clean ground; and (iii) the isolating bentonite
cut-off wall would be constructed around building # 31 to the depth of
During several years PCP
and local environmental authorities conducted the expertise of JV Evrohim
design and also were looking for the source to fund the works on
demercurization of the buildings and the industrial site of PCP (all valuable
equipment, non-ferrous metals and commodity metallic mercury were utilized
straight after the chlor-alkali production closure in 1993-1994). The turning
point was the support of Demercurization Project by Governor of Pavlodar Oblast
Mr. Daniyal Akhmetov (at present he is the Prime-Minister of
In 1999 French state
company BRGM were carrying out the mission of French Government which the
Government of Kazakhstan applied for the help to (Resolution of the Government
of Kazakhstan #179 from February 26, 1999). BRGM proposed “the Project for the
prevention of mercury pollution at JSC “Khimprom”,
However, in the course
of further negotiations the proposals of BRGM were modified. The new version of
proposal assumed that using $8.2 million of French loan for the first stage:
(i) the status of mercury pollution in site of PCP and around would be
investigated; (ii) the concrete floor of electrolysis factory would be covered by
engineering capping; (iii) the building of electrolysis factory would also be
isolated by cut-off wall; and (iv) the technology of thermal mercury extraction
from contaminated ground and construction materials would be developed using
the pilot tests [34-35]. In such situation the
In 2001-2002 the area of
mercury contamination was studied by the consortium of European and

The revision of JV
“Evrohim” design was carried out in 2003 and had the principal idea to cancel
any attempts to extract mercury by any means from the concrete floor of
building #31, and highly contaminated grounds and construction materials.
Instead it was decided to construct the isolating cut-off wall to the depth of
underlying bed not only around the building #31 but also around the other
principal sources of mercury pollution (four sources in total). It also was
decided to make special engineered capping above the areas isolated by cut-off
walls in order to avoid the mercury transport to atmosphere. Therefore the
revised JV “Evrohim” design lay in the isolation and containment strategy
instead of the strategy of excavation and recovery of Hg. The newly formulated
concept was approved by the
In 2003-2004 the Program
of Post-containment Mercury Monitoring for the period of 2005-2020 was
developed in AIPET by request of PCP. This Program is stipulated for a small
amount of funding from the budget of the

Collaborator Trevor W. Tanton will be a
consultant during coordination and conduction of fieldworks as well as during
the stage of risk assessment from contamination by mercury and oil products. He
will also participate in drawing up the recommendation on management of such
risk.
The Partner will carry out activities,
monitoring and audit in the whole duration of the project. The Partner will
evaluate the possibility of further cooperation after the project finish date.
Foreign Partner Paul Randall is a key person in
achieving the goals and objectives of the project. Close interrelation is
anticipated between the scientists of research laboratories of
During sampling and chemical analyses the
methods recommended by US EPA will be used as well as standard procedures on
Quality Control/Quality Assurance accepted in the West. Determination of
mercury in solid samples will be carried out using AAS analyzer (Lumex RA
915+); AFS analyzer (PS Analytical Millennium Merlin System) will be used for
Hg determination in water samples and biological tissues. Chemical analysis of
oil products’ concentration in water will be conducted using GC Perkin Elmer
Clarus 500.
The following methods will be used for the
chemical analyses and quality control:
·
US EPA method # 1631
Revision E – for the determination of total Hg in water;
·
US EPA method # 7474 –
for the determination of total Hg in biological tissues;
·
US EPA method # 7471
Revision B – for the determination of total Hg in soils, sediments and bottom
deposits;
·
US EPA method # 9071 Revision A – for the extraction of petroleum and oil
products;
·
US EPA method # 1664 –
for the determination of N-Hexane extractable oil products by extraction and
gravimetry;
·
Method of the
Massachusetts Department of Environmental Protection (MADEP) – for determination
of extractable petroleum hydrocarbons (EPH) by Gas Chromatography.
Assessment and management of risk associated
with groundwater contamination will be carried out using hydrogeological models
received by means of the ModFlow GMS 5.0 software. The preliminary assessment
of risk (Tier 1 of risk assessment) posed by mercury contamination of pastures
and fish will be conducted using the monitoring of the level of mercury
pollution and subsequent comparison of pollution indices with existing state standards
and guidelines values.
