Abstract

The Ground water and Surface water are the major sources for the drinking water. In Telangana, Isnapur areas, Hyderabad District, the major water supply is contaminated due to the rapid increase of population, industrial growth, activities of the people with industrial effluents discharged on the lake water and on the soil. The uncontrolled hazardous waste sites are involved in contaminating the ground water and surface waters.  The Surface water and groundwater are contaminated it is difficult to restore the water quality. It is very much essential to protect the surface water bodies in order maintain the ecological balance and provide proper management plans for the conservation and water management. The Environmental problems are highly complex, and management procedures have to be developed to achieve coordination for need to initiate the environmental measures for protection. The contaminant in this lake was predominantly 2,4D and 2,6D organic compounds, which termed as the hazardous in the lake water. The study of Isnapur Lake water included physico-chemical and suitable remediation techniques were identified.   A very less value of dissolved oxygen and a high amount of values for hardness, chlorides, TS, TDS were observed during all the seasons. GIS will serve as important computational tool and facilitate multi map integrations and will also assists in data capture and process. By using RS and GIS mapping its shows the lake water quality analysis effectively. The Satellite data and GIS has good potential to transfigure the groundwater and surface water monitoring and management in the future.
