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. 2018–Dec. 2020): 1 ppb. EPA's current action level is 15 ppb; its health goal (MCLG) is 0.

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 →
