Abstract

In the present study, the physico chemical parameters of ground water (Bore well) of different highly populated residential area of Pollachi were analysed during May 2013 to April 2014 at monthly interval. The comparative results showed that the electrical conductivity (1350 - 1510 mMhos/cm), pH (6.9-7.2), calcium (69-90 mg/l), magnesium (29-37 mg/l), sodium (189-206 mg/l), potassium (6-9 mg/l), bicarbonate (610-660 mg/l), sulphate (20-23 mg/l), chloride (158-170 mg/l), nitrate (0-1 mg/l), total dissolved solids (820-842 mg/l) and total alkalinity (510-542 mg/l). The parameters pH, sulphate, chloride and nitrate were found within the recommended standards of WHO and ICMR. The analysis revealed that electrical conductivity, calcium, magnesium, total dissolved solids and total alkalinity were exceeded the drinking water standards.
