Abstract: As most of the surface water has been contaminated by anthropogenic intervention in India for all human beings safe drinking water is yet not available. In places of mining it is absolutely necessary to assess and monitor the quality groundwater to check its suitability for industrial use and drinking and agriculture production along with suitability for domestic use and drinking water purpose.The objective of the scientific observation in the study area are focused to ensure that the people, livestock, or crops of the area are not affected by contamination of the water. In the physical parameter analysis and chemical parameter analysis in the laboratory parameters such as pH, EC, TDS, Total Hardness, Alkalinity, cations and anions in water were determined. To find out the influence of monsoon on groundwater over six years of observation from 2010 to 2016 two sets of sampling, one in pre monsoon and another in post monsoon was done every year. From the analytical data facies and water types were determined. Water chemistry of the area seems to have influenced by Limestone mining in the area. Preventive measures and proper management strategies are required as fluoride content in groundwater is more than 1 mg/l in many samples
