Hydrochemical analysis and groundwater quality in Trichirappalli district, Tamil Nadu - An geomatic based aproach

Water is one of the most valuable natural resources, which supports human health, economic development and ecological diversity. Because of its several inherent qualities (Eg., consistent temperature, wider spread and continuous availability, excellent natural quality, limited vulnerability, low development cost, drought reliability etc.). It has become an immensely important and dependable source of water supplies in all climate regions including both urban and rural areas of development and developing countries. Major portion of the surface water and ground water is being consumed by agriculture and the left over portion is used for industrial and domestic requirements Trichy has located in centre of Tamilnadu (India). Its border populated upto Perambalur district. The people in the 40 villagers use kollidam river water and the ground water for drinking. Lot of work has been done and published already on the ground water quality of many villages in trichy district. But there is a need to undertake the study to assess the drinking water quality. Hence water samples of twenty five villages were subjected to physio-chemical parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), Calcium (Ca), Magnesium (Mg), Sodium (Na), Potasium (K), Chloride (Cl), Sulphate (SO4) were analyzed and were compared with standard prescribed by WHO and suitable suggestion were made. The correlation coefficients were calculated for water quality assessment.
