C Sakthivel, A Thirunavukkarasu
A study was carried out in a granite mining area in the Sankari area to evaluate the current status of physicochemical contaminants and their sources in groundwater. The groundwater samples collected from mining and residential areas at ten (18) different locations were analysed. The physico-chemical parameters such as pH, DO, EC TDS, alkalinity, turbidity, calcium hardness, magnesium hardness, total hardness, nitrate, fluoride, iron, and chloride have been analysed. The results showed that among the mining and residential locations, many of the estimated physico-chemical parameters were similar. WHO and APHA standards. The basic physiochemical properties of the collected groundwater samples have been analysed. Comparative data analysis for the samples based on the analysed parameters has been made. The highest possibility of water quality issues that affect the day-to-day consumption of groundwater for the domestic needs of the people has been emphasized.
