Water Quality Snapshot: PHILIP

PHILIP is a local-owned community water system that delivers drinking water to 759 residents in PHILIP, South Dakota (Haakon County) through 480 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 89 total violations for this system , of which 70 (79%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 15 monitoring and reporting violations are on file. The most recent violation on record dates to 2002.

The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 46 violations (TT, health-based). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 64.6 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across South Dakota, EPA tracks 654 public water systems serving 915,901 people, with 56,254 cumulative violations and 8,399 health-based violations on record. About 92% of systems in the state carry at least one violation, and state-wide the average per system is 86 violations. PHILIP's 89 violations sit above the South Dakota average. Statewide, 42 of 49 UCMR5-tested systems have reported PFAS detections (85.7%).
