Abstract :

A comparative study was undertaken to assess the groundwater quality for drinking purposes. One tube well selected was situated near a sewer while there was no sewer in the vicinity of the other tube well. The water samples were collected and analyzed for physico?chemical viz., temperature, turbidity, pH, EC, FCO2, DO, B.O.D., C.O.D., CO3?, HCO?, Cl?, Ca++, Mg++, TH, Na+, K+, SO4, SiO3, NO3, PO4, Fe, Cu, Cr, Zn and Pb and bacteriological characteristics i.e., MPN index/100 ml. for a period of two years on monthly basis. The study has revealed some alterations in physico?chemical parameters and MPN of water in the first case, while in the second case, the water quality was within permissible limits. On the basis of microbial count analysis, the water quality of first tube well (IIIM/RRL, Jammu) comes under the category of unsatisfactory (MPN >10/100ml.) due to effect of sewage drain. Qualitatively, E. coli and Klebsiella / Klebsiella and Citrobacter recorded their perennial presence in the first/second i.e., Coffee house (Jammu Press Club) tube well, respectively, during both the years. Quantitatively, the MPN index/100 ml. ranged between 7 and 18/6 and 17 in the water samples of first tube well and 1 and 2 / 1 and 2 in the second tube well during the first/second year of study. MPN count recorded summer and monsoon increase and winter decrease. According to standards recommended by British Ministry of Health (1957), the water quality comes under the category of unsatisfactory (MPN >10/100 ml.) in case of first and satisfactory for the second tube well.
