Water Quality Snapshot: NWREC/OSU
NWREC/OSU is a state-owned non-transient non-community water system that delivers drinking water to 40 residents in AURORA, Oregon (Clackamas County) through 1 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 77 total violations for this system , of which 3 (4%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 70 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.
The most frequently cited contaminant at this system is Coliform (TCR), recorded in 9 violations (MR). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.
Across Oregon, EPA tracks 2,518 public water systems serving 4,005,242 people, with 206,659 cumulative violations and 20,339 health-based violations on record. About 99% of systems in the state carry at least one violation, and state-wide the average per system is 82.1 violations. NWREC/OSU's 77 violations sit below the Oregon average. Statewide, 30 of 125 UCMR5-tested systems have reported PFAS detections (24%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
