- Lead: 90th percentile of samples taken at customer taps. Results depend on the home's plumbing.
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.
Hardness
Hardness is not reported in the latest CCR. Hardness not reported for this system; softener sizing uses a regional default of 11.7 gpg until a CCR value is reviewed.

Monitoring and reporting violations (71)
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.
