I have carried out research work entitled: ENVIRONMENTAL STUDIES OF WATER QUALITY FOR DOMOSTIC, IRRIGATION AND INDUSTRIAL PURPOSES AS WELL AS GEOCHEMICAL STUDIES OF HEAVY METALS CONCENTRATION IN SOIL SAMPLES IN AND AROUND NALGONDA DISTRICT ANDHRA PRADESH INDIA.The study has been carried out with the objective to find out the causes of soil and water pollution and its impact on human society. Vicinity of many industrial zones leads to high level of metal toxicity that is derived from the poorly treated effluents discharge on the open land. The study was under taken on soil and water contamination in Chinnaeru River basin to determine the extent and distribution of heavy metals to delineate the source as geogenic or anthropogenic.There is no treatment plant in that area. This area is mostly affected by industrial activity and urbanization. The industries like Automobile, Battery manufacturing and Petrochemical are releasing the highly hazardous waste. The data indicates that the soil in the study area is significantly contaminated.The contaminated soil was assessed on the basis of Geoaccumulation of Index, Enrichment Factor, Contamination Factor and degree of contamination.
