STUDY OF GROUND WATER QUALITY WITH SPECIAL REFERENCE TO ARSENIC OF DISTRCT, BHOJPUR, BIHAR (INDIA)

SANJAY KUMAR VERMA, V K PRABHAT

Abstract

The present investigation deals with ground water quality with special reference to Arsenic of five different areas of Bhojpur town and its adjoing area i.e. karari (S1), Mahuli (S2), Rampur (S3), Ander (S4) and Bandha (S5). The groundwater parameters such as temperature, pH, turbidity, alkalinity, dissolved oxygen, biochemical oxygen demand, total hardness, calcium, magnesium, phosphate, sulphate, arsenic, iron, chloride and fluoride were estimated in the samples to evaluate their quality. The data of physico chemical parameters are compared with WHO (1992) and IS: 10500 standards for drinking water. Our result revealed that concentration of DO, BOD, Total hardness, Calcium, magnesium, sulphate, turbidity, alkalinity, phosphate, iron and chloride are within permissible limits and Iron, phosphate are negligible in comparison to permissible limits whereas the concentration of Arsenic is higher at sampling areas S2 ,S3 and S5 .The concentration of Arsenic varied from 0.2 to 07 mg/l and the permissible limit is, 0.05 mg/l (50 μg/l). as per suggested by Guidelines for drinking water quality, 4th edition WHO,2011 . The higher concentration of Arsenic needs proper treatment before the use for drinking purposes and irrigation purposes. Finally it can be suggested that an intensive study may be carried out before the domestic consumption.
