Lead & Copper

Measure Result EPA action level Status Monitoring period
Lead (90th percentile) 0.001 mg/L 0.015 mg/L Below action level 2025-12-31

These are 90th-percentile results across sampled household taps, not a single measurement, and neither lead nor copper has a Maximum Contaminant Level. Lead reaches tap water from household plumbing rather than from the treatment plant, so a result below the action level does not guarantee your own tap is below it. Source: EPA SDWIS, Lead and Copper Rule sampling.

Lithium

This system was monitored for lithium and none was detected at or above EPA's minimum reporting level of 9 µg/L.

Lithium has no federal drinking water limit. The Health Reference Level is a non-regulatory screening value from EPA's CCL 5 process, not an enforceable standard, and a result above it is not a violation. The figure shown is the highest single detection reported for this system; EPA compares averages, not maxima, when it reports national statistics.
