Assessment of the Physico-chemical Status of Ground Water From Some Selected Open Wells in Bhimavaram Town, West Godavari District

摘要

Physico-chemical analysis of open well water samples was carried out from 14 sampling sites in Bhimavaram town of Andhra Pradesh for the month of October 2013. The parameters determined heavy metals, such as Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Hg, Pb and U using (ICP-MS) spectrometry. Ancillary data included pH and electric conductivity. The concentrations of V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd and U were below detectable limit. The correlation coefficients were calculated for water quality assessment. The relative concentration of the trace metals in open well water observed in the sequence of Fe＞Hg＞Pb＞AI. The results showed that out of 14 wells, 4 of them were strongly polluted, but they require certain levels of treatment before use.
