Groundwater Quality Assessment through Hydrogeochemical Analysis: Implications for Drinking Water and Pollution

Abstract

The quality of groundwater and its geochemical features as a source of drinking water are under investigation in the current research. The physical characteristics, cation, and anion chemistry of 201 samples of groundwater were determined. The investigation was conducted in the Southern Indian province of Tamil Nadu, specifically, the Karur District, which is situated between 10°30′ – 11°00′ North latitude and 77°45′ – 78°30′ East longitude, and covers an area of approximately 2900.63 km2. Safe drinking water standards established by the WHO were used for comparison. The majority of samples on the Gibbs plot are inside the rock dominance zone, showing that the chemical of the rock interacts with the groundwater to affect the chemistry of the groundwater. The study region’s Piper plots reveal that most of the samples contain CaCl or CaMgCl. The WQI results for almost all samples were either “excellent” or “good,” suggesting they are suitable for human consumption.
