Abstract :

Groundwater is the main resources for drinking, irrigation and domestic purpose. Now a day groundwater contaminated by natural and mainly contaminated by anthropogenic activities. This paper mainly focused analysis of the Water quality is very important to preserve and prefect the natural eco system. For this study 48 groundwater samples were collected of plain area in Upper Manimuktha Sub basin, Vellar River, Tamil Nadu, India. The study area lies between 78°42’ to 78°59’ E and 11°42’ to 11°59′ N latitude, covering a total area of 497.11 sq.km in which plain area 309.92sq.km and hilly area occupies 187.19sq.km. The groundwater samples were collected from study area based on equal grid method and analyzed using standard methods. The physico–chemical parameters are assessing based on the inverse distance weighted method into GIS techniques. For the water quality, following parameters have been considered Viz. pH, total dissolved solids. Electrical conductivity, total hardness, calcium, magnesium, sodium, potassium, bicarbonate, chloride, fluoride, sulphate, nitrate etc. All the parameters were compared with the WHO and BIS standard and for each samples consider the Water Quality. Based on water quality all the samples in the study area fall in permissible limit except few samples.
