K.; Singh, Rajesh; Rao, Y. R. S.; Tyagi, J. V.; Jain, Sharad K. Abstract: Water is important for hydration and , consequently, for life. It is also essential in food preparation and cooking, sanitation and hygiene and for different uses. The safe drinking water must be free from all hazardous materials and contaminant. Nature has provided enough drinking water resources for living organisms through rain, springs, rivers, lakes/ponds and subsurface resources. However, due to non availability of safe drinking water at all places and limited drinking water supply, people started opting commercial products for treating their water supply at domestic and community level without knowing much about its technologies adopted in these commercial products and assuming that the treated water from these products are a symbol for high purity potable water. Different chemicals such as pesticides, disinfection by product are the subject of interest while some other constituents are out of focus. There are certain elements which play an important role in human health, representing essential elements for human body activities. Calcium and magnesium are major representatives of these types of constituents. 2019-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/710 Title: जल संरक्षण : क्या करें और क्या नहीं करें Authors: National Institute of Hydrology 2018-01-01T00:00:00Z
