ESOP evaluates groundwater quality around SRS to develop background water quality information to support DHEC and SRS groundwater monitoring programs.

ESOP uses a network of around 101 wells within 25 miles of the SRS boundary (Groundwater Monitoring locations). The network consists of public supply, private, irrigation, and monitoring wells. 

Due to having a large network, ESOP samples wells are on a five-year cycle. Wells are analyzed for selected radiological constituents.

ESOP’s groundwater results enhance current DHEC water quality data. Wells will continue to be sampled to ensure the public that SRS is not having an impact on off-site groundwater quality.
