College Pithoragarh In the present investigation, the physicochemical and microbiological properties of water in the hilly area of Champawat district Uttarakhand, India in pre-monsoon season of 2017 were studies. For the study, the variation of parameters was recorded in natural sources of water and their corresponding supply water. The analysis was carried out for the parameters like Colour, Odour, Turbidity, pH, Temperature, TDS, EC, Total Hardness, Total Alkalinity, Cl-, F-, SO42-, NO3-, PO43-, Total coli and E. coli. In the study, 3 the pH was found to be slightly alkaline, the high value of Turbidity was observed in few sites and some analysed samples were also contaminated by total coliform and E. coli. By comparing the studied parameters, the result showed minor differences between the parameters of source water and supply water. The study concluded that either the value of physicochemical parameters falls under the permissible limits of WHO and BIS, but some sampling sites are microbial contamination was observed. http://pubs.sciepub.com/aees/9/2/15/aees-9-2-15.pdf physicochemical and microbiological properties variation parameters natural source water supply water
