### Model of transport of pollution during remediation pumping and reinjection of treated water

The quasi-stable concentration value is reached already after 21 days of simultaneous pumping and recharging. The picture presents the spread and the degree of pollution. This figure documents a fairly irregular spread of pollution. The aquifer between HSJ-1 and HM-3 and HM-2 is cleared up to a concentration level of 1 mg/l. On the opposite side of well HSJ-1 there is a maximum concentration over 1.6 mg/l. The pollution after 21 days is on average lower than after pumping only from well HSJ-1 for 2 months.
