Water Quality Snapshot: 5 CEDARS

5 CEDARS is a native american-owned community water system that delivers drinking water to 150 residents in DEMING, 10 through 43 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 293 total violations for this system , of which 33 (11%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 212 monitoring and reporting violations are on file. The most recent violation on record dates to 2024.

The most frequently cited contaminant at this system is Groundwater Rule, recorded in 28 violations (TT, health-based). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.

Across 10, EPA tracks 158 public water systems serving 142,574 people, with 31,953 cumulative violations and 1,055 health-based violations on record. About 98% of systems in the state carry at least one violation, and state-wide the average per system is 202.2 violations. 5 CEDARS's 293 violations sit above the 10 average.
