摘要：Groundwater quality problems have emerged in many geographical areas due to natural environmentalprocesses and human intervention in the geosystems. Groundwater is the major resource for drinking and domesticpurpose in most parts of the world as it is available inexpensively near to door step and free from pathogenic germs.Chemical contamination of drinking water especially fluoride is a major concern in drinking water supply. Goodquality of drinking water is essential for human life. The spatio-temporal variations in rainfall, local distribution ingeological and geomorphic composition of various units have led to uneven occurrence and distribution of groundwaterresources. Telangana state has been improved occurrence of fluorosis day by day, due to moderate concentration offluoride in ground water. The fluoride is occurring predominantly in the younger granitic terrain like Alkali FeldsparGranite and Grey Biotite Granite.The Remote Sensing imagery with its synoptic coverage, acts as a tool for finding suitable solution whencombined with conventional data. Fluoride concentration maps were using Remote Sensing & GIS techniques. Anintegrated Remote Sensing & GIS study has been taken up for chityala mandal for studying the hydro geomorphic unitwise ground water quality evaluation and its impacts. The district is underlain by different rock types like granites(85%) and gneisses (8%); and rest of the area is underlain by intrusive. The ranges of fluoride in the district are varyingfrom 1.25 to 3.10 ppm. The maximum permissible limit for fluoride in drinking is 1.50 ppm as per Indian DrinkingWater Standards (BIS Guideline-IS: 10500: 1991). Most of the quality affected sources are having marginally highconcentration of fluoride (1.50-3.00 ppm). It is observed that the fluoride contamination is more on the north andeastern parts. Remedial measures like supply of safe drinking water and construction of rain water harvesting structuresto minimize the moderately high concentration of fluoride are proposed.
