Description :
Hydrogeochemical analysis was carried out in Kera river basin of Patan taluk, Maharashtra, to assess ground water quality for its suitability for drinking and irrigation purpose. Twenty one representative post monsoon,shallow aquifer groundwater samples were collected from both bank of river and analyzed for major physico-chemical parameters like pH, EC, TDS, total hardness, Ca2+, Na2+, K+, Mg2+, NO3, Cl, SO4 and HCO3and all the results were compared with standard limits recommended by World Health Organization (WHO, 1984) and Bureau of Indian Standards (BSI, 2012).Study reveals that only groundwater samples from Ker and Patan-1 are not suitable for drinking and domestic purpose as higher concentration of parameters like Ca2+, Cl, NO3and HCO3are observed. Patan-1, Patan-2 and Tamkane are the places where total hardness is found to be above permissible limit. Cl- in village Ker sample is also crossing the permissible limit for drinking purpose. Piper trilinear diagram was used for identification hydrochemical facies and most of samples are of Ca-HCO3, mixed Ca-Na- HCO3, NaCl and mixed Ca-Mg-Cl type. SAR, SSP, KR and PI calculated for all samples and study reveals that samples from Bibi, Keral, Divashi-Khurd, Ker and Mestiwadi are not suitable for irrigation purpose. Keywords: Kera; physico-chemical parameters; hydrochemical facies; SAR; SSP; KR.
