Safe drinking water is the important need for every human being. Water may be contaminated by natural sources or by industrial effluents. One such contaminant is fluoride. The problem of excess fluoride in ground water was detected in many states of India. Till 1999, 17 states have been identified with the problem of excess fluoride in ground water sources. Several materials like aluminium salts, calcined alumina, magnesia, lime, activated carbon sulphonated carbonaceous materials, and ion exchange resins have been screened for their utility in defluoridation of water. On the basis of results and extensive investigations, different researchers had developed a simple and economical domestic defluoridation processes. This article attempts to critical review of the past work on defluoridation studies by using conventional and unconventional materials, and to compile the various pros and cons of these defluoridation methods including Nalgonda, Activated Alumina, bone char, fly ash, brick, and reverse osmosis.}, URL ={https://www.jhrr.org/article.asp?issn=2394-2010;year=2014;volume=1;issue=1;spage=1;epage=4;aulast=Ingle;t=6}, eprint ={https://www.jhrr.org/article.asp?issn=2394-2010;year=2014;volume=1;issue=1;spage=1;epage=4;aulast=Ingle;t=6} }
