Abstract

The present proposed research study is aimed at characterization of ground water samples collected near Municipal dump site during Pre and Post seasons for assessing its quality for drinking and domestic utility. The physicochemical parameters analyzed include pH,EC,TDS,TH,TA,Co3-2,HCO3-,Cl-,SO4-2 , PO4-3, Na, K, Ca+2 and Mg+2. pH ranges in the permissible limits while TDS in majority samples exceeded the permissible limits of IS:10500-1992. The higher values of Total Hardness and Ca ion concentration indicate that the waters were not suitable for domestic use. Though the values of SO4-2, are within the permissible limits, the waters are not suitable for drinking or domestic purposes due to the presence of soluble solids. Further the waters were analyzed for bacterial species. E Coli, Klebsiella, Pseudomonas, Proteus and Enterobacter were identified and their presence indicates the bacterial contamination. Hence these waters are unsuitable for drinking as well as for domestic purposes and are to be perfectly treated, if necessary for consideration for utility.
