Abstract
The present study was aimed at assessing Trace element ground water chemistry and drinking purpose. Totally 20 groundwater samples were collected from different locations in Gomukhi sub basin, Vellar basin Tamil nadu. The groundwater sample collected during the February 2014. The toposheets is 58I/9, 10, 13, 14 and 58M/1, 2. The toposheets 1:50,000 scale. Geologically the study area chonockite and Hornblende biotite gneiss is the dominant of covering major parts of the study area, Followed by the Fissile hornblende gneiss, Basic dykes some parts coverd. The present investigation was based on the occurrence of trace elements such as Fe, Mn, Cr, Cu, Ni, Co, Zn, Pb, and Cd in groundwater samples, concentration ranging from 0.003 to 0.186, 0.016 to 0.718, 0.912 to 0.965, 0.009 to 0.091, 0.143 to 0.332, 0.012 to 0.301, 0.002 to 1.006, 0.260 to 0.474 and 0.023 to 0.052 respectively. The analysis of ground water results were compared to WHO (2011) drinking water standards. The concentration of Fe, Cu, Zn, elements in permissible limit, and Cr, Ni, Pb, Cd elements in above the permissible limit.
