Water Quality Snapshot: Salt River Public Works

Salt River Public Works is a native american-owned community water system that delivers drinking water to 20,951 residents in Scottsdale, 09 through 1,303 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 197 total violations for this system , of which 29 (15%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 95 monitoring and reporting violations are on file. The most recent violation on record dates to 2022.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 20 violations (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 231 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across 09, EPA tracks 323 public water systems serving 555,721 people, with 48,296 cumulative violations and 3,354 health-based violations on record. About 97% of systems in the state carry at least one violation, and state-wide the average per system is 149.5 violations. Salt River Public Works's 197 violations sit above the 09 average. Statewide, 30 of 41 UCMR5-tested systems have reported PFAS detections (73.2%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
