EPA lab monitoring (UCMR 5)
EPA UCMR 5 monitoring (Apr. 2024–Feb. 2025) detected 2 of the 30 monitored chemicals in this system's samples. Highest reported PFPeA result: 3.4 ppt.
| Chemical | Highest result | EPA legal limit (MCL) | EPA health goal (MCLG) |
|---|---|---|---|
| PFPeA perfluoropentanoic acid | 3.4 ppt | No federal MCL | — |
| PFHxA perfluorohexanoic acid | 3.1 ppt | No federal MCL | — |
UCMR 5 results are monitoring data, not a compliance determination. PFAS compliance is governed by separate EPA drinking-water rules. Some PFAS rule changes are proposed for 2026 — see what's proposed.
Lead at customer taps
Lead at sampled customer taps, 90th percentile (Jan. 2018–Dec. 2020): 0 ppb. EPA's current action level is 15 ppb; its health goal (MCLG) is 0.
Lead is regulated with an action level rather than a standard MCL. EPA's lead action level is 15 ppb today; the Lead and Copper Rule Improvements lower it to 10 ppb starting Nov. 1, 2027.
Violations on the federal record

What the numbers mean
EPA uses two different benchmarks: the legal limit (MCL) and the health goal (MCLG). They are not always the same number. Read EPA's explanation →
