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.

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 →
