Detection of Some Bacterial &Chemical pollutants of the wells drilled water at many Areas in Baghdad
AbstractAbstract The research includes a study on bacterial contamination and certain chemical contaminants of water wells drilled in different areas of Baghdad. Five regions have been selected of the wells drilled in different places in the depths ranged between depths (5-15 meters), the Karrada, Jadiriyah, Mansour, Baya´a and Ghazaliya. The results of bacteriological tests showed that the water wells drilled were not suitable for household use compared to the specifications of Iraq and the more wells with bacteriological contamination was in the Jadriya, followed by areas of Karrada, Almansor count was more likely to fecal bacteria (Mpn/100ml) of these areas are (90,40,40),respectively while it was (Mpn/100ml) in Baya & Ghazaliya (0,0).The results also showed that that some chemical tests of water in the areas studied were not in accord with Iraqi specification, especially for drinking water due to high concentrations of total dissolved salts (TDS) in mg/L. The wells water of the Jadria has the highest proportion (TDS=1800mg/L), followed by the wells of Baya, Karrada, Mansour and Ghazaliya with a TDS value (1700, 1500, 1400, 1200, mg/L) respectively. Other chemical tests such as the pH and Turbidity of water wells were in accordance with Iraqi Wells Water Specification.
