College of Engineering, University of Basrah. Iraq ABSTRACT Once contaminants reach the aquifer, the mitigation thereof becomes expensive and often not readily possible. A proactive approach to the assessment of aquifer vulnerability to contamination, rather than a reactive approach, is thus of utmost importance for the future sus-tainability of our groundwater resources. The main object of this study is to estimate the groundwater vulnerability in Bahr Al-Najaf area, middle of Iraq. Data in the present study were of two types: spatial data and non- spatial data, there are obtained from wells logs, pumping test results, geological maps and hydro-geologic reports, and soil investigations. The scope of pollution was analyzed by developing the seven map layers and generating the DRASTIC technique. The vulnerability index was obtained by DRASTIC technique that varied from (70 to 140).

INTRODUCTION In dry regions of the world, groundwater is an invaluable prove-nance for water. If groundwater is contaminated, may cause an environmental degradation and health risk. Groundwater can be exposed for a wide range of activities or human actions that may lead to the leaching of pesticides and fertilizers, disposal of sewage, and waste materials. Prohibition of groundwater pollution is the best way to effective and efficient environmental administration, as the groundwater treatment is slow and costly. In order to conserve groundwater resources and areas exposed to pollution, as a result of human activities, must be
