  • Copper: 90th percentile of samples taken at customer taps. Results depend on the home's plumbing.
  • Gross Alpha: Compliance uses the running average of gross alpha minus uranium. Shown value is the highest lab result; the adjusted average is 0.0 pCi/L after subtracting 14.74 pCi/L for uranium.
  • 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.
