Environmental Impact of Ground Water in Dindigul District Tamil Nadu, India

Abstract

The present study is attempted to evaluate the extent of pollution of ground water and pond water due to the percolation of sewage and hospital waste water in and around Pillayarpalayam located near Trichy road of Dindigul. The ground water quality is very much affected due to discharge of hospital waste water and Sewage water from the Multi-specialty hospital with five hundred beds in to the pond. Sewages and hospital waste water are discharged in to streams, which drain into Maruthanikulam pond, thereby polluting the ground water sources, for the past thirty years. Pollution is caused by hospital waste including soaps, detergents, bleaching powder, acids, clinical agents, agents septic tank wastages, vegetables, polythene bags, insecticides, Antiseptics, bandages, disposal cups, plates, needles, syringes, bottles, cottons. The hospitals need a large amount of water for various purposes and depend on the ground water sources for their daily requirements. The discharged sewages and waste water from the hospitals are percolated into the ground and causes ground water pollution. Thus the ground water sources are exploited to their fullest potential and polluted to a greater extent. The effect of hospitals waste water have damaged the environment and affected the people living on the back side of the hospital. Hospital wastes and sewages are affecting the environment and health of the people. The hospital waste water has affected the health of the people. The people are also prone to epidemic diseases, like Cholera, jaundice and Malaria. This study was carried out to assess the magnitude of the water pollution problem in Pillayarpalayam area due to the impact of hospital waste water. The study was attempted understand the toxic effects of sewage water and hospital waste water among the people nearby Pillayarpalayam pond. Since the pond water and the ground water become unfit for human consumption, an attempt was made to find the extent of water pollution by analyzing the various water quality parameters in eleven sites. Water sample were analyzed and compared with BIS limit for water standards. Investigation of physico-chemical characteristics of ground water, grounds were under taken. The utility pattern of groundwater in and around Pillaiyarpalayam area is undertaken to find the suitability of drinking water. The water is found to be hard with high TDS, hardness and salinity. People are not able to drink the water due to poor taste. From the water samples collected the water quality parameters like PH conductivity, Chloride, Fluoride, Nitrate, Phosphate, Calcium, Magnesium turbidity were analyzed. The study reveals the high degree of water pollution by comparing the various waste water quality parameters with BIS permissible limit. Hence the polluted water is subjected to water treatment. Contaminated water is treated using reverse Osmosis system. To reduce the TDS in ground water, but this water cannot be used for drinking purpose.
