Water Quality Summary

BROOKINGS is served by 6 public water systems with a combined service population of 23,603 people, and has 724 EPA Safe Drinking Water Act violations on record. None of those violations are health-based — the records reflect missed monitoring or reporting deadlines rather than a contaminant exceeding safe levels. BROOKINGS's violation count is 862% above the national average for South Dakota. Contaminants associated with violations include 1,1,1-Trichloroethane, 1,1,2-Trichloroethane, 1,1-Dichloroethylene, 1,2,4-Trichlorobenzene, 1,2-DIBROMO-3-CHLOROPROPANE.
