ThesisItem Open Access Studies on the effects of industrial effluents on water sources of Siidcul region, Dehradun(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Baljinder Singh; Kashyap, P.S.Due to rapid industrialization on one side and increasing population on the other, the demand of water supply has been increasing tremendously. Moreover a major portion of this limited quality of water is polluted by sewage, industrial waste and a wide range of synthetic chemicals. Fresh water which is a precious and limited vital resource needs to be protected, conserved and used wisely by man. But unfortunately such has not been the case, as the polluted lakes, rivers and streams throughout the world testify. For our study, the sources selected are generally used for domestic, industrial and drinking purpose. A total of 10 groundwater sites which included 7 borewell sites apart from 3 handpump sites were studied and analyzed. For surface water evaluation, 5 designated locations which are approximately 5 km apart from one another were taken into consideration. In total 15 sites were studied for their physical and chemical properties. The samples from each site were collected during winter season, post winter rains and during the summer season in 2019-20. Post sample collection, the various physical and chemical parameters like pH, TDS, EC, Acidity, Alkalinity, CO2, TH, Ca2+ , Mg2+ , Na+ , K+ and Cl– were tested using standard APHA methodology and thereafter the results were compared with the standard guideline values recommended by Bureau of Indian Standard (BIS) for drinking purpose.
