QUALITY ASSESSMENT OF PHYSICO-CHEMICAL PARAMETERS IN DRINKING WATER AT PULICAT LAKE FISHERMEN VILLAGESR. Sumithraa, A. Vinoth and N. ThirunavukkarasuAbstract In recent trends water pollution plays a major role in human health and life threatening issues both directly and indirectly related with water utility. Present study based on the analysis of physiochemical parameters in drinking water supplies in various fishermen villages Sathankuppam, Edamani, Thoniravu, Pulicat, Goonankuppam, Arangamkuppam, Vairavankuppam and Koraikuppam around fishermen villages of Pulicat lake. Physiochemical parameters like pH, total dissolved solids, total suspended solids, conductivity and turbidity were recorded from the drinking water samples. Presence of minerals and heavy metals and total bacterial count were also investigated in the water sample. Results show highest value noticed in pH (8.17) at Vairavankuppam, TDS (1589 ppm), TSS (203.1ppm) and conductivity (2788 µs) in Goonankuppam and turbidity (2NTU) from Thoniravu and Goonankuppam. The concentration of minerals, heavy metals and bacterial contamination also monitored. Based on the water quality results it proves to be not good for the domestic usage. More knowledge and awareness are needed for the public to avoid water borne diseases. |
