Water Quality Snapshot: NORTH PARK PUD

NORTH PARK PUD is a local-owned community water system that delivers drinking water to 6,708 residents in HOUSTON, Texas (Harris County) through 2,236 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 40 total violations for this system , of which 0 (0%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 40 monitoring and reporting violations are on file. The most recent violation on record dates to 2021.

The most frequently cited contaminant at this system is Mercury, recorded in 1 violation (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 30.6 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Texas, EPA tracks 7,351 public water systems serving 33,253,313 people, with 746,210 cumulative violations and 162,945 health-based violations on record. About 90% of systems in the state carry at least one violation, and state-wide the average per system is 101.5 violations. NORTH PARK PUD's 40 violations sit below the Texas average. Statewide, 1,068 of 1,147 UCMR5-tested systems have reported PFAS detections (93.1%).
