The main pollution source is placed in the neighbourhood of remediation wells in the south-east corner of the industrial zone. The source was assumed to be permanent. The modelling of transport of pollution was done for the time of 50 years. In this time the front of the pollution reaches the water recipient and 50 years is the time of functioning of the factory and the time of permanent polluting of groundwater. In 50 years the pollution front reached the pond in an average concentration 1%.
