Contamination in drinking water affects society and the phenomenon becomes a global problem. Some contaminants are general and some depend on the geographical location. The extent of the contamination also depends on geographical location. Fluoride is such a contaminant presence of water causes Fluorosis. The maximum permissible limit of fluoride in drinking water is 1.5 mgL-1. Endeavors are going on in chemical Laboratories stored throughout the globe for defluoridation of drinking water and several such procedures have been developed and recommended. But another side of the problem is disposal of the affluent containing fluoride which would be responsible for newer pollution. One way of getting rid of fluoride-rich sludge is to use the same in manufacturing brick. Mixing sludge with clay not only removes the hazards of further pollution but also imparts special characteristics to bricks thus manufactured.
