From last decade, the worth per barrel of drinking groundwater has outperforms the value of a barrel of oil in several areas of the world. Therefore, appropriate evaluation of groundwater potential and supervision practices were need of the day. Physicochemical assessment of groundwater in the Tirunelveli district, were determined with the parameters, like BOD, COD, Calcium (Ca), Chloride (Cl), Sulphate and (SO4) were analysed quantitatively using standard methods. The investigations indicated that the concentration variations were recorded in site to site and in sample to sample and also season to season. The present study reveals that the water is contaminated at selected points which are not suitable for drinking. The pulp of paper mill, textile industry and temple waste and small scale industries are added to the sampling points. These are the main pollutant sources of thamirabharani river in addition to anthropogenic activities. Tirunelveli Corporation, supplies water to towns from thamirabharani river. The analyses results shows, that all the groundwater quality parameters on certain station found higher than the prescribed limit of WHO.
