A.P.India.Abstract: The small portion of available fresh water with great concern, since the quality of water is offor human consumption is being contaminated by vital importance for mankind and it is associated withvarious anthropogenic sources at a very alarming human welfare. With this view, the presentrate. With this view an attempt was made to assess investigation was carried out to assess thethe quality of groundwater in rural areas of groundwater quality, as groundwater is the onlyVijayawada by examining various physico – source for drinking, domestic and as well as otherchemical parameters such as colour, turbidity, purposes in the study area.odour, pH, electrical conductivity, total dissolvedsolids, alkalinity, hardness, nitrate, sulphate, Study Areachloride, fluoride, iron and magnesium, to check A part of Vijayawada and its rural areasthe suitability of water for human consumption. such as Ramavarappadu, Prasadampadu, EnikepaduExcept hardness all most all parameters in the and Nidamanuru constituted in the study area, whichcollected ground water samples are within the are located at 160311N longitude and 800371Epermissible limits given by WHO, ISI ICMR. latitudes of krishna district, A.P.
