According to the World Health Organization (WHO) more than 80% diseases of mankind are water borne. The present research work is focused on characterization of water samples collected before and after treatment from Rural Water Supply (RWS) schemes located at Revenue Mandal Head Quarters Ganapavaram and Nallajerla of West Godavari district during pre and post monsoon seasons for physicochemical parameters Viz., pH, Electrical conductivity (EC), Total Dissolved solids (TDS), Total hardness (TH), Total Alkalinity (TA), Na, K, Calcium and Magnesium, Chloride, Sulphate, Nitrate, Fluoride, Phosphate and Metal ions Viz., Li, Be, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Ag, Cd, Cs, Ba, Tl, Pb and U to evaluate the quality of drinking waters. The study results indicated that the waters are with slightly alkaline nature. TH and TA values of post monsoon samples exceeded the permissible limit while other parametric levels of TDS, Na +, K+, Cl-, F-, NO3-, SO42- , PO43- values are within the permissible limits.
