RESULTS AND DISCUSSIONS
EC
To study the water quality status of Shahpura lake, thirteen surface water quality monitoring stations were chosen at different points of the lake and sixteen ground water quality monitoring stations in the fringe area (where source water is mainly ground water) were finalized. The methods of water analysis were used as prescribed by APHA (American Public Health Association) water environment federation and National Environment Engineering Research Institute (NEERI), Nagpur. Water samples were collected during the winter season, 2011 from the selected stations. The analysis of the following physico-chemical parameters was carried out: pH, Electrical Conductivity(EC - µmho/ cm), Total Dissolved Solids(TDS - mg/L), Ammonia (mgNH3-N/L), Nitrate (mgN/l), Total Phosphorus (mgP/L), Iron (mg/L), Fluoride (mg/L), Chemical Oxygen Demand (COD - mg/L), Dissolved Oxygen (DO – mg/L ), Total Hardness (T.Hard. - mgCaCO3/ L), Calcium (mg/L), Magnesium (mg/L), Chloride (mg/L), Sulphate(mg/L), Carbonate (mg/L), Bicarbonate (mg/L) and Coliforms.

METHODS
Station
nutrient load in the lake is very high and hypereutrophic conditions are prevailing. Hence periodic monitoring and preventive measures are required to save the lake from eutrophication. Although, few work has been done to understand the status of the lake, no study has been made on the pollution effects of the lake on the ground water quality of the adjoining areas. The polluted lake water may enter into aquifer or ground water body of fringe areas specially the downstream areas by percolation and influent seepage. At least sixty thousand population resides in the fringe area and is dependent on the ground water, moreover the Chunabhatti area acts as a ground water sanctuary for the town as the drinking water is supplied to the different parts of the city through the water tankers filled from the tube wells daily. Therefore the assessment and monitoring of its water quality is very important. Hence a serious need is felt for the study of the water quality which could prove beneficial for the large number of people.
