Naturally-Occurring Fluoride in Groundwater

Understanding, managing and treating geogenic fluoride for small water systems. We look at geologic and geochemical conditions that can result in high fluoride concentrations in groundwater. We look at a variety of treatment options, including well modification to seal off high-F zones, blending options and treatment plant options, including reverse osmosis and activated alumina. We also look at two case studies of high-fluoride in groundwater and the solutions implemented in those cases.
