Abstract
The groundwater is one of the most important sources for drinking water now a day. However due to the dumping of municipal wastes and agricultural wastes into the ground and industrial waste water into the river leads to the contamination of groundwater. Thus the analysis of the groundwater quality is very important to protect the human health. So the present study deals with the physico-chemical characteristics of ground water quality in Villupuram, Vikravandi and Tindivanam towns in Villupuram district. Water samples were collected from different identified bore wells for the purpose of studying the quality of groundwater during JAN 2016. The bore wells from which the samples were collected are extensively used for drinking purpose. It has been proved from the present investigations that value of few parameters TDS, Total Hardness, Calcium, Sulphate, Chloride, Nitrate, Alkalinity, Magnesium, Ammonia and Electrical conductivity are fall out of the permissible range with reference to WHO guideline levels for drinking water. The most serious pollution threat to groundwater is from TDS, Total Hardness, Alkalinity, Calcium, Chloride, Nitrate, Sulphate and Calcium, which are associated with sewage and pollution of industrial waste. Hence, suggested to take proper care to avoid contamination of groundwater pollution through periodic monitoring of the water quality.
