Geochemical Studies of Ground Water at the Eastern Side Dindigul Rock Fort Due To The Impact Of Sewage And Industrial Effluent

The investigator has made an attempt to study the impact of untreated sewage water and industrial effluent in the groundwater sources from the houses located at the foot hills of Dindigul Rock fort. The pond has become a collection of sewage water from Dindigul town. About ten ponds in Dindigul town discharge through several canals and finally reach the Rock fort pond behind Taluk Office. As the result the water in the pond as well as the groundwater sources around different residential area like Kamarajapuram, reaches high degree of pollution. Ground water analysis at four different sites at four directions reveals that the water quality parameters are higher than the permitted level. As per CPHEEO standard specifically high turbidity, high TDS and higher Electrical conductivity values indicate that the water cannot be used for domestic purpose. The adjoining groundwater sources are mostly affected and the water becomes very salty with very high TDS. Hence the polluted water is suggested to water treatment using Reverse Osmosis System.
