Study of Water Quality in and around Vriddhachalam in Cuddalore District, Tamil Nadu

Physico-chemical quality of the groundwater samples of bore wells in and around Vriddhachalam of Cuddalore district is studied. Three samples, one from Vriddhachalam town, one from Erumanur village and the third one from M. Patti village were collected for the study. The parameters observed were pH, electrical conductivity, total dissolved solids, total alkalinity, total hardness, calcium, magnesium, nitrate, chloride, sulphate, sodium, potassium and fluoride. The results reveal that most of the physico-chemical parameters for the second and third samples have the values above the permissible limit, but below the excessive limit. Hence, they can be used for drinking purposes. The values of these parameters except TDS are above permissible limits and below excessive limit for the first sample. The TDS exceeds the excessive limit, hence, it has to be pretreated by reverse osmosis before drinking.
