Statistical study on physicochemical characteristics of groundwater in and around panjapur area near korai river, Tamil Nadu, India

Abstract

Groundwater is the most precious gift of nature to living beings, particularly to the mankind and is essential for life. In recent years, rapid development has created an increased demand for drinking water, which is increasingly being fulfilled by groundwater abstraction. The groundwater samples collected from a panjapur area near korai river Tiruchirappalli district Tamil Nadu India. Groundwater samples collected seasonal variation Pre monsoon (May), Monsoon(August), and Post monsoon (November) during the Year 2014. Ten groundwater samples analyzed for major physicochemical parameters such as pH, Electrical Conductivity, Total DissolvedSolids, Total Hardness, Dissolved Oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, Bicarbonate, Calcium,Magnesium, Sodium,Potassium, Sulphate,Chloride and Nitrate,  in order to understand the different geochemical processes affecting the groundwater quality. The analytical data were interpreted using WQI. The Calculated WQI value is (101.6). The analytical results indicate the majority of the groundwater samples are unsuitable for drinking purposes. The typical sewage comprising of domestic and other waste is discharged directly into the open land without any proper treatment will cause contamination. This contamination poses serious health impacts in the local residents.The correlation and regression provide an excellent tool for the prediction of parameter values within a reasonable degree of accuracy.
