EPA lab monitoring (UCMR 5)
EPA has no UCMR 5 (PFAS and lithium) monitoring results on file for this system.
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. 2022–Dec. 2024): 8 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.

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 →
