Lead Summary
Detected: 0 mg/L (ppm)
Found at 2 providers
Iron
Detected: 71 UG/L (ppb)
5/20/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 26 UG/L (ppb)
5/20/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Lead
Detected: 1.5 UG/L (ppb)
6/9/2025
A metal that can leach from old pipes, solder, and fixtures. Current medical guidance holds there is no truly safe level of lead exposure, especially for children and pregnant women.
Barium
Detected: 130 UG/L (ppb)
6/9/2025
Zinc
Detected: 8.6 UG/L (ppb)

Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Totalhaloaceticacids (HAA5)
Detected: 12 UG/L (ppb)
8/4/2025
TTHM
Detected: 43 UG/L (ppb)
Found at 2 providers
A group of disinfection byproducts formed when chlorine reacts with organic matter. Long-term exposure above the legal limit has been linked to increased cancer risk in some studies.
Chloroform
Detected: 23 UG/L (ppb)
Found at 2 providers
One of the individual trihalomethane disinfection byproducts, formed when chlorine reacts with organic matter.
