PHYSICOCHEMICAL ANALYSIS OF GROUNDWATER QUALITY OF VELLIANGADU AREA IN COIMBATORE DISTRICT, TAMILNADU, INDIA

The global climatic change has its impacts on the water crisis in some areas and Coimbatore is one of the places where the groundwater levels are declining every year. In the recent past, drilling of the bore-wells increased massively in search of water since most of the open wells dried up in Velliangadu area of Coimbatore district. Open well water used to be the primary source of water for irrigation purpose till last decade but more and more bore wells were drilled in search of water up to 1000 feet underground. Since the drilled bore wells were of a minimum of 300 feet and a maximum of above 1000 feet it was quite interesting to analyze the physicochemical properties of groundwater and help the farmers to gain knowledge on water quality parameters. The quality of groundwater in Velliangadu area was analyzed by determining the pH, Hardness, Alkalinity, Total Dissolved Solids, Chloride content and Electrical Conductivity. Since all the parameters were in good agreement with the standard values given by various organizations it is concluded that the groundwater quality of Velliangadu area is good.
