Bar length is the highest result in the last 36 months as a share of the federal limit (MCL, or action level for lead and copper). The dark tick marks the limit. Gross alpha is compared after subtracting uranium, as DEQ does for compliance.

Aesthetic and unregulated

Taste, odor, staining or scale, not health limits. Bars use the EPA secondary standard where one exists.

ppb = parts per billion (µg/L), ppm = parts per million (mg/L), ppt = parts per trillion. ND = not detected above the lab's reporting limit. MCL = federal maximum contaminant level; AL = action level for lead and copper (90th percentile of home taps); aesthetic = secondary standard for taste, odor or staining, not health. Bars show the highest result in 36 months as a share of the limit.

A required sample or report was late or missing. These do not mean a contaminant was found, but a system that skips monitoring has gaps in its record.
