Evaluation of drinking water sources of Dehradun and Haridwar with identification of source of contamination

Abstract

Evaluation of drinking water quality is one of the most essential requirements for safety and good health of human life. Water pollution has become a serious threat now days, and water sources of Uttarakhand state are also not insulated from this problem. For the deterioration of drinking water quality of drinking water sources both geogenic as well as anthropogenic activities are among responsible factors. The present study culminates the qualitative and quantitative water quality analysis of 39 and 17 drinking water sources of Dehradun and Haridwar, respectively for 29 parameters for drinking water using advanced analytical techniques focusing on identification of sources and causes of pollution of studied sources. newlineDuring the course of the study, assessment of drinking water quality of 39 water sources of Dehradun and 17 water sources of Haridwar for 29 physico chemical and bacteriological parameters have been carried out. To identify the sources as well as causes of contaminations in water sources, various advance statistical techniques such as have been implemented and are thereby drawn and discussed. newlineResults of the analysis revealed that three water quality parameters namely turbidity, FC and TC have been found as common problem water quality parameters values were more than permissible limits in Dehradun during two seasons of both years of study. Whereas, only one water quality parameter that is turbidity was observed as common problem water quality parameter in Haridwar during the study period. newlineResults of the study culminate that during 2014 and 2015 in PRM and POM seasons, most of the analysed drinking water sources of Dehradun and Haridwar districts were suitable and safe for drinking purpose. Only certain water sources of both districts were found contaminated and require some economical pre-treatment processes before used as drinking purposes newline newline
