Elaboration of Aquifer System and its Application for Protection of Groundwater contamination in the Dhamrah Kas Basin, Wah Cantt. Pakistan.

Interdisciplinary investigational techniques (Hydrogeogical reconnaissance, Geophysical survey, Testhole drilling, installation of tubewells and capacity tests0 were used for the interpretation of subsurface hydrogeology of the Dhamrah Kas Basin. A multilayered aquifer system spread over an area of about 150 Sq. Km was proved with the help of 20 test holes and 10 dug wells extending to a depth of 300 to 600 feet. The aquifer is classified as multilayered  semiconfined fresh body with an average well capacity of 250-350 gallons. The shallow aquifer (A-layer) is in severe danger of contamination near northern boundary of the basin through induced recharge from a polluted nullah. The bacterial contamination (Coliform and Facecal Coliform) has polluted shallow aquifer very severely. Treatment and protectional measures are discussed, particularly for elimination of physical and bacterial pollution.
