| description | A hydrogeologic study has been adopted to conceptualize the concepts of groundwater levels lowering in swamped area of Tyass, middle of Iraq. 2D dimensional groundwater model and, mitigation model has been used to mitigate the aquifer against high salinity and chemical pollutants by the mitigation theory of heterogeneous subsurface media, which depends upon physical and mathematical derivation, evaluation of chemical pollutants and total dissolved salts (TDS) of subsurface water before and after mitigation process. The water table level was lowered up to 2.43m at the center of a pumping well of abstraction discharge (400m3/day) obtained after 2755days in steady state. The ions concentrations of iron (Fe), zinc (Zn), mercury (Cu), cadmium (Cd), lead (Pb) and TDS in groundwater of 0.4, 3.25, 1.15, 0.004, 0.033 mg/liter and 7000ppm respectively were reduced to less than the allowable limits according to WHO of 0.3, 3, 1, 0.003, 0.01mg/liter, 1200ppm respectively by adding 0.2WD of fresh water from Hillah river and using maximum no. of pumping wells of (19 at April) after 240 months. The mitigation period was reduced to 120 months when the addition of solvent volume was doubled. Mitigation process in heterogeneous against high saline levels and chemical pollutants has been proven a good tool for the rehabilitation of polluted aquifers. |
