Arsenic and fluoride are key issues in the global water challenge as they exist above the World Health
Organization (WHO) recommended limits of 0.010 mg/L and 1.5 mg/L, respectively, in the natural
drinking water sources of many regions of the world. The suitability of using several types of bone char
as a sustainable removal technology for arsenic and fluoride in remote areas of developing countries is
evaluated. The results suggest that 500˚C is the ideal charring temperature for fish bone char based on
removal capacity and aesthetic concerns, such as water discoloration and smell, and that there is no
significant competition found when removing fluoride and arsenic simultaneously. Current water projects
often fail after one to three years for a variety of reasons. Therefore, implementation strategies will also
be discussed.
