Abstract: Pedapadu is a Mandal in West Godavari District of Andhra Pradesh State, India. Pedapadu Mandal Head Quarters is Pedapadu town . It belongs to Andhra region ..Agriculture is the main stay of population in the district. The district is having both surface and ground water resource potential. The delta area is mainly served by surface irrigation, whereas in the upland areas of the district the irrigation is chiefly by ground water. Physio graphically the district is divided into 2 natural regions. viz., Alluvial plain and upland areas.The different type of soils encountered in the district are red soils, black cotton soils, deltaic alluvial soils and coastal sands. In general, the ground water is suitable for drinking and irrigation purposes in crystallines, sedimentaries while that occurring in alluvium the water is not suitable for drinking purpose and irrigation purpose under ordinary conditions. Water pollution is one of the major and most critical issues in India, as almost 70 per cent of the surface water resources and various groundwater reserves are contaminated by biological, toxic, organic and inorganic pollutants. Deep tube wells, hand pumps and private bore wells are the main sources for extraction of groundwater in the Pedapadu mandal to cater the water demand of the population. It is in this context, the ground water quality is determined in Pedapadu mandal in the upland area of the West Godavari dt. In Physico-chemical analysis , various quality parameter are measured including pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total hardness(TH),content of calcium (Ca2+),magnesium (Mg2+), chloride(Cl-), sulphate (S0 2-), Iron (Fe), DO, BOD, COD, Total alkalinity (TA) and Nitrate (NO 2-) concentration present in ground water. Also all parameters were compared with ICMR standards of water quality. In the present research paper water samples of Pedapadu mandal was classified on the basis of TDS and TH.
