EVALUATION OF WATER QUALITY ROLE ON ENVIRONMENTAL IMPACT ASSESSMENT STUDY

The Aim of the present study was to know the water quality role in the study area. Water is a vital natural resource which forms the basis of all life. We depend on water for irrigation, industry, domestic needs. The study area is near power house kothagudem area. The thermal plant uses 15000 tonnes of coal and discharges 5000tonnes of fly ash and bottom ash daily to the disposal site. The waste is dumped into a dam founded on metamorphic rock. However the waste hills formed, the water level reaches the ground surface. Ultimately adversely affecting the quality of ground and surface waters. Once the ground water is contaminated, its quality cannot be restored by stopping the pollutants from the source, its therefore becomes imperative to regularity monitor the quality of ground water and surface water and to device ways and mean to protect it. Contamination of ground water and surface water by domestic, industrial effluents and agricultural activity is serious problem faced by developing areas. Burning coal produces huge quantities of toxic waste which is stored in large coal ash ponds and ash dump sites. these coal waste impoundments are long term hazards to local communities and water supply as they can break, flood or seep into groundwater. keeping this in view the present study has been attempted. The present study was under taken to ascertain groundwater pollution of part of kothagudem town. Groundwater and surface samples were collected from predetermined locations and analysed for physical and chemical parameters. the data and the results of the investigation area are presented and discussed.
