Surface water bodies are the water present on the surface of land like oceans, rivers, streams, lakes and other natural water courses. Lakes in urban and pre-urban areas are an important interface between planning and ecology which demands environmentally responsive strategies. The increase in population by leap and bounds is threatening the pollution of water resources badly. Because of Urbanization and industrialization the disposal of waste water and sewage has become the major problem in cities where population has increased drastically over the decades. Surface water bodies quality monitoring using GIS are not new. In fact it was practiced in India and other countries long back. The Present study deals with spatial analysis of water quality for 27 different surface water bodies located in and around Greater Hyderabad Municipal Corporation (GHMC). The 27 surface water bodies were delineated using satellite images of Google Earth, water samples were collected from 27 surface water bodies and the parameters such as pH, Total Dissolved solids, Co3 as CaCo3, HCo3 as CaCo3, CL, F, No3 as N, So4, Na, K, Ca, Mg, Total Hardness as CaCo3 has been analyzed, the analytical report of water samples were compared with BIS (Bureau of Indian Standards) permissible limits and by using spatial analysis in GIS, the spatial extent of water quality has been monitored. The main objective of the study is to know water quality of different surface water bodies and spatial extent of water quality for pre-monsoon seasonby using ArcMap. It is estimated and concluded that the quality of water from 27 different surface water bodies varies comparatively with the permissible limits given by Bureau of Indian Standards and the spatial extent of water quality is varying with respect to the parameter and its values. By analyzing the water samples of 27 different lakesfor post-monsoon seasons, the water quality Index can be known for different lakes by comparing the quality of pre and post monsoon seasons and also the spatial extent of pre and post monsoon seasons can be monitored.
