Monitoring of stream water physico-chemical characteristics and heavy metal concentration is necessary to establish the levels of contamination in wastewater. With increasing urbanization and industrialization, there has been a rapid increase in industrial effluent discharge into the water bodies, leading to increased pollution load. Groundwater quality in Tiruchirappalli City, Tamilnadu, India, was studied and major dissolved constituents including heavy metals of concern such as chloride, fluoride, nitrate, nickel, copper and iron have been documented in this paper. Thus, this study helps to determine the groundwater potential and aquifer characteristics of the study area.
