Arsenic in Drinking Water
Studies have indicated that arsenic concentrations greater than the EPA maximum concentration limit of 10 micrograms per liter occur in numerous aquifers throughout the country. Successful prevention of public exposure to arsenic in groundwater resources is dependent on scientifically based strategies for site remediation and water resource management.
EPA scientists are focusing their research efforts on optimizing remediation technologies and management approaches to protect groundwater resources from arsenic contamination. EPA is collaborating with the U.S. Geological Survey, Oklahoma State University, and the City of Norman, Oklahoma, to find a cost-effective solution for removing arsenic from the water supply wells in the City of Norman.
