Water Quality Snapshot: Spencer Road PUD

Spencer Road PUD is a local-owned community water system that delivers drinking water to 5,607 residents in Houston, Texas (Harris County) through 1,869 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 305 total violations for this system , of which 2 (1%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 297 monitoring and reporting violations are on file. The most recent violation on record dates to 2013.

The most frequently cited contaminant at this system is Methoxychlor, recorded in 17 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 7 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 27.2 ppt (parts per trillion). 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.
