Abstract: The drinking, borewell and sewage water in the Sanmugasikamani Nadar(S.N) street, Naivatti Nadar(N.N) street and Thiruthangal area of Sivakasi has been studied. The various constituents monitored include the physicochemical characters like pH, total solids, total dissolved solids, total suspended solids; chemical parameters like total alkalinity, acidity, free CO₂, dissolved oxygen, total hardness, calcium, magnesium, chloride, salinity and bacterial parameters like standard plate count (SPC), total coliform count (TCC), faecal coliform count (FCC), faecal streptococcal count (FSC). Most of the physicochemical characters of drinking and borewell water were within the ISI permissible level. However in water samples from all the sites, bacterial count exceeded the recommended permissible level of WHO. Introduction of sewage into the drinking and borewell water was the main reason for the bacterial contamination. The boiling of water is therefore advisable before consumption.? The physicochemical and bacterial characters of the sewage water were unworthy. The sewage water recycling was necessary to minimize the water born diseases.
