Abstract:

A detailed GIS based study on hydrochemistry of groundwater in Chinnar sub-basin of Cauvery river, Tamil Nadu, India has been carried out to assess the quality of groundwater for determining its suitability for drinking purpose. Further, the spatial variation of various groundwater quality parameters over the basin has also been studied for November
2010. Fifty seven groundwater samples were collected and analysed for pH, conductance, total dissolved solids, total hardness, calcium, magnesium, fluoride, iron, carbonate, bicarbonate, total alkalinity, chloride, sodium, potassium, sulphate and nitrate etc., The values analyzed were evaluated in detail and compared with WHO water quality standards. TDS widely varied from 301 mg/L to 1505 mg/L with an average value of 703.51 mg/L. About 87% of the samples and spatially 789.32 km2 areas are within the maximum allowable limit for drinking (1000 mg/L). Groundwater
of the basin belongs to hard to very hard water category since the total hardness (TH) exceeds the permissible limit of 500 mg/L prescribed for drinking water. Magnesium content in groundwater fifty samples out of 57 samples exceeded the maximum allowable limit of 50 mg/L. Concentration of potassium ion in groundwater ranges from 3 mg/L to 24 mg/L with an average value of 9.11 mg/L. Thirty nine samples out of 57 samples exceeded the maximum allowable limit of 10 mg/L. Fluoride is (> 1.5 mg/L) in groundwater at 5 locations, which may cause dental and skeletal fluorosis.
