Abstract :

Islamshahr is located 30 km away from the capital. Over the past decades, it has grown quickly, but irregularly; a growth which has led to the pollution of ground water at which those living in the region have protested. No doubt, it is their right to have access to pure healthy water. Since the only source of drinking water provision for the villages of Islamshahr is ground water resources (i.e., wells), it is obviously important to study the quality of the water of these wells. In this research, which extended for 14 months from December 2005 to January 2006, the quality of drinking water of the region from the microbial point of view was determined twice through sampling and bacterial tests on the water of 14 wells situated in the residential areas of villages. Coliform pollution is reported in Nezamabad, Raziabad, Rrahimabad-shokrabad, Islamabad and Jafarabad Jangal villages. The excremental coliform pollution is not seen in the area except for one case in Islamabad village. As microbial pollution exists in some wells and as the only source of drinking water in Islamshahr is ground water, it is necessary to always pay attention to the quality of drinking water in this area.
