Fluoride contamination of groundwater is a major, well-known health concern, that still does not have any highly effective or sustainable technologies to remedy it. The World Health Organization suggest the Nalgonda method, but this techniques has several major flaws including a treatment efficiency that is limited to only 70 percent, and a large dose of aluminum sulfate, which causes sludge disposal problems. Instead, we intend on using Polyaluminum Chloride (PACl) as a coagulant to which the fluoride can both adsorb to and coprecipitate with. Our objective for this semester is to build adjust the physical system with a sand filter to trap the coagulant and being the adsorption and coprecipitation. to use a floc blanket to remove fluoride, find the new optimal PACl dosages, and prepare for the EPA P3 competition,
