The EPA selected GSWSA to participate in the Unregulated Contaminant Regulation 4 (UCMR 4) program in 2020 for Horry County. Unregulated contaminants are constituents in the water that do not have a drinking water standard set by the EPA. The purpose of monitoring for these contaminants is to help EPA decide whether the contaminants should have a standard. For more information on the contaminants or UCMR 4, please contact SC DHEC at (803) 898-4300. For a complete list of parameters tested during the UCMR 4 sampling event, please call Customer Service at (843) 234-8460.
