ASSESSMENT AND UTILIZATION OF GROUND WATER SAMPLES AS POTABLE WATER NEAR A DUMPING YARD OF NANDYAL, KURNOOL DISTRICT, ANDHRA PRADESH, INDIA

Abstract

Groundwater is an important source of water supply throughout the world. These sources are quite vulnerable to pollution and are irreversible and reclamation of polluted ground water sources is very difficult. Ground water samples were collected from the 10 different locations around the dumpsites of Nandyal, during January–February 2014. The quality was assessed in terms of physical–chemical parameters such as pH, TDS, EC, Turbidity, Total Hardness, Total Alkalinity, Chloride, Sulphate, Phosphate, Nitrate, Dissolved Oxygen, Fluoride, Calcium, Magnesium, Potassium and the metals like Copper, Zinc and Manganese using various analytical techniques. Faecal coliform were estimated in water samples collected from different sampling areas. It was found that the underground water was contaminated at few sampling sites which exceed the permissible limit of WHO Standards.
