The management of ground water quality is a major environmental challenge in now a days. Monitoring the different sources of pollutants load contribution to the ground water is quite difficult. The main objective of this present study is the Assessment and analysis of impurities of Ground water in Sunder nagar Town of Mandi District of Himachal Pradesh India . To determine the impurities of ground water in Sunder Nagar area, the following Physical as well as the Chemical processes were conducted to determine various physical and chemical characteristics. The five sites were chosen randomnly for taking sample of ground water i.e Sample1 is taken from village Bherjwanu, which is an agriculture area. Sample 2 is taken from DhanotuNH23(National Highway) ,Sample 3 is taken from chambi area(which is an residential area).Sample 4 is taken from Jangam bag the place of JAMADAGNI RISHI .He is one of the Saptarishis in the seventh, and he is the father of Parashurama. Sample 5 is taken from Sukhdevvatika,(Which is place of sukhdev muni). All of these sample were collected from Tehsil Sunder nagar in order to evaluate the Ground water suitability for drinking and agricultural purpose. For this purpose, we have conducted Physical process test i.e. pH (alkalinity test), turbidity, conductivity, Total dissolved solids (TDS) ,Temperature test. The chemical Process tests includes Residual chlorine test, Hardness of water, Alkalinity of water ,Chloride, Presence of Fluoride, Iron, Nitrate. These all tests were performed in IPH (Irrigation & public health department) Lab of SunderNagar circl
