Forecast of changes in underground waters quality on the territory of the water catchment area of the Lesnaya and the Muhovets rivers

The geo-migration modelling of the change in underground waters quality on the territory of Lesnaya- Muhovets interfluve in the zone of the water intake influence of Brest city has been done. According to the results of the modelling the forecast maps of the underground water pollution of ground, Paleogene-Middle Quaternary and Oxfordian-Cenomanian aquiferous water complexes (AWC) for the period from 5 up to 100 years during the natural regime of underground waters filtration and in the condition of the central water intake operation of Brest city have been created.
It has been established that temporary pollution migration in natural conditions is utterly slowly. The ground, Paleogene-Middle Quaternary and Oxfordian-Cenomanian AWC undergo to pollution during a forecasting period. Upper Proterozoic-Lower Cambrian AWC being in the zone of impaired water exchange does not undergo to a negative impact.
The water intakes of Brest city have not made a significant influence on the scopes of the underground waters pollution of the ground and Paleogene-Middle Quaternary AWC. The main changes connected to the exploited Oxfordian-Cenomanian AWC. Underground waters sampling from this complex in an amount of 221.7 thous. m3/day increases the pressure flow gradients and accordingly underground waters speed motion. During 100 years pollution forecast forefront from ‘Zapadny’ pig breeding complex can reach ‘Zapadny’ water intake line
Obtained modelling results have interest for the grounding of arrangements management on underground waters condition on the territory of Lesnaya and Muhovets rivers water catchment area.
