Drinking Water Quality Monitoring

Drinking water quality is evaluated to ensure that radiological constituents have not affected municipal drinking water systems adjacent to the Savannah River Site (SRS). Eighteen of these systems are groundwater-fed and four are surface water-fed systems. These systems serve approximately 285,000 customers with approximately 109,000 receiving their water from groundwater sources. ESOP staff collect monthly drinking water composite samples from drinking water treatment plants that use the lower portion of the Savannah River as a source, and biannual grab samples from selected municipal and large community drinking water systems within 30 miles of SRS. Samples are analyzed for gross alpha, nonvolatile beta, gamma-emitting radionuclides, and tritium.
