GROUND WATER QUALITY The quality of ground water is generally alkaline and suitable for drinking and irrigation purpose with few exceptions Type of Water : Ca-HCO3 and Ca-Cl 12. DYNAMIC GROUND WATER RESOURCES- (2013) Annual Replenishable GW : 844.64 MCM Resources Gross Ground Water Draft : 451.31 MCM Projected Demand (Domestic + : 27.21 MCM Industrial) Stage of Ground Water : 53.43% Development Category Safe 13. MAJOR GROUND WATER PROBLEMS AND ISSUES Although a modest area in Jalna district is under canal command of various irrigation projects and the area is showing declining trend of ground water levels due to exploitation of ground water for irrigation and other purposes at a faster rate. There is much scope for conjunctive use in such areas. The conjunctive use of water is recommended in this area. Ground water quality is adversely affected at many places due to high concentration of some parameters specially nitrate. Adequate sanitary protection to the wells may be provided to control the nitrate contamination. 14.
