Assessment of Water Quality using Water Quality Index : A Case Study

Abstract

Water found in the natural environment is never chemically pure. It always contains one or more dissolved substances. Chemically pure water does not naturally exist, nor is it necessary for sustaining life. When rainwater initially falls from the sky, it is relatively pure, but as it passes through the atmosphere, it absorbs gases and captures particles present in the air. The specific substances and their concentrations that water picks up during this process influence its overall quality. The groundwater quality in the study area of Vadlamudi, Guntur District, Andhra Pradesh, was evaluated by analyzing various chemical parameters. These parameters include pH, conductivity, total dissolved solids (TDS), total alkalinity, total hardness, chlorides, nitrates, and iron. The assessment was conducted at eight distinct sampling stations across the study area to determine the overall water quality and its suitability for different uses.
