Evaluation of Groundwater Quality and its Suitability for Drinking and Agriculture use (Case study: Astaneh Ashrafiyeh)

ABSTRACT:Groundwater is an essential and vital component of any life support system. It is not only the basic need for human existence but also a vital input for all development activities. Use of fertilizers and chemical pesticides that contain various combinations of pollutants is and to create a serious environmental concern. This study evaluated the chemical contamination of ground water in some local wells. In this study, three wells (representative wells area) were selected. After 48 stages sampled monthly during spring and summer parameters EC, pH, TDS, TH, and SAR were assessed. The results were compared with well control and agricultural water standards. Results showed that the water wells in the study area compared with the control wells and water standards, with high levels of agricultural water standards are more parameters. The study area due to high water and most chemical parameters, not potable and irrigation of agricultural use and with limits the principal use of pesticides, to prevent contamination of soil and water resources is very vital.
