5 Test results
5.1 Groundwater monitoring
The main groundwater monitoring objectives are as follows:
Monitoring of groundwater levels and quality;
Timely detection of groundwater quality changes to take the measures required to
prevent any potential impact on water quality.
The groundwater level was determined based on its depth below ground level.
Two monitoring wells used to monitor the levels and chemical composition of
groundwater are located near the leach fields of the Odoptu-2 (North) WS.
The test well is 15 m to the south of the leach fields.
10
The baseline well is 15 m away from the northwest corner of the leach fields
(upstream along the groundwater flow).
The wells drilled near the temporary waste storage site (TWSS) at the Odoptu-2 (North)
WS are intended for monitoring of the chemical composition and levels of the groundwater in
the potential TWSS impact area.
The baseline well is located upstream of TWSS (along the groundwater flow) and
designed for monitoring of the chemical composition of groundwater before it flows
past TWSS.
The monitoring well is located downstream of TWSS (along the groundwater flow)
and designed for monitoring of the chemical composition of groundwater after it flows
past TWSS.
Observation well flushing at Odoptu-2 (North) Well Site
In 2018, the Odoptu-2 (North) Well Site observation wells were flushed.
The ice plugs in the TWSS wells were also drilled out in 2018. The primary goal of these
activities was to restore/maintain the observation wells in order to accomplish operational
control and monitoring program.
The work was performed in June - July of 2018.
5.1.1 Water Table Monitoring
The groundwater level was determined based on its depth below ground level.
Measuring instruments: electrical level gauge EU-100.
Parameters to be measured: depths of occurrence.
The results of level measurements in wells are presented graphically in the figure below
(Figure 5.1).

Groundwater level fluctuations in monitoring wells near Odoptu-2 (North) WS leach
fields are minor and seasonal.
5.1.2 Groundwater quality monitoring
Monitoring of groundwater chemical quality indicators was performed in monitoring wells
near leach fields located at the Odoptu-2 (North) WS.
Groundwater for laboratory analysis was sampled quarterly.
Sampling was performed using the PE-1105 sampler after well flushing and water level
recovery.

Measured pH values range from 5.4 to 7.0 and are consistent with the typical values for
natural waters. Based on рН values, groundwater in the monitoring well in the first quarter was
found to be slightly acidic (pH = 5.0-6.5), in the second quarter –neutral (рН = 6.5-7.5) before
well flushing and slightly acidic after well flushing; in the fourth quarter - neutral both before
and after well flushing. In baseline well No. 5, groundwater in the first quarter was found to be
neutral, while in others –slightly acidic (pH = 5.0-6.6) both before and after flushing.
Groundwater conductivity ranges within 100-791 µS/cm.
Water analysis results showed that the characteristics in the monitored well did not
exceed that in the baseline well.
5.2 Monitoring of subsoil and interbed crossflows
Monitoring of subsoil and interbed crossflows, areal spread of drilling and other process
wastes within the site, as well as spread of formation water injected into a dedicated well was
performed in 2018.
The above scope included monitoring of the level and quality of groundwater in
monitoring wells at the Odoptu-2 (North) WS.
Groundwater for laboratory analysis was sampled quarterly in 2018.
Sampling was performed using the PE-1105 sampler after well flushing and water level
13
recovery.
Samples were stored and preserved per GOST 31861-2012.
The results of level measurements in wells are presented graphically in the figure below
(Figure 5.2-1).
Figure 5.21: The groundwater level trend graph in monitoring wells near leach fields at the Odoptu-2 (North) WS.
Groundwater level fluctuations over the entire monitoring period ranged:
in well D-1 – from 10.18 m to 11.5 m.
in well D-2 – from 7.33 m to 8.97 m.
Groundwater level fluctuations in monitoring wells at the Odoptu-2 (North) WS are minor
and seasonal.
Groundwater level and quality measurements demonstrates that value fluctuations do
not exceed the natural changes in groundwater levels at the monitoring site, and groundwater
chemical composition in the specified wells shows that the groundwater is not affected by
drilling wastes, other process wastes, and produced water injected into the dedicated well.
5.3 Monitoring of injected wastewater quality
Wastewater, process wastes, and drilling water is injected in injection well at the Odoptu-
2 (North) WS.
Before injecting wastewater is sampled to determine its quality.
Immediately after sampling, the water was placed in a dedicated sample storage
container (per GOST 17.1.5.04-81).

interval 1700-2450 m (TVDSS) with no direct contact with the above-mentioned environments.
According to the process flow diagram, drilling and other process wastes are injected
into an injection well with no negative effect on surface ecosystems (soils, surface and
groundwater).
5.4 Monitoring of gray water quality
Wastewater quality control includes monitoring wastewater composition and physical
and chemical properties at treatment facility inlets and outlets to assess operating efficiency of
these facilities.
