Abstract
Groundwater chemical quality studies were carried out in part of Nalgonda district of Andhra Pradesh. where fluoride incidence had been earlier reported. The concentration of TDS, TH, Ca, Mg, Na, K, Cl, SO4, NO3, and F of the borewell waters were compared with drinking water standards of Bureau of Indian Standards (BIS) and World Health Organization (WHO). The results indicate that the concentrations of certain quality parameters of the groundwater are exceeding the recommended limits. The GIS analysis revealed that while the Northeastern and Southwestern areas indicated moderate to high levels of pollution, the Northwestern and southeastern region indicated relatively less pollution. Appropriate measures needed to ensure safe drinking water are discussed.
