Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Lead
Detected: 5.6 UG/L (ppb)
9/12/2025
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.
Copper, Free
Detected: 89 UG/L (ppb)
9/15/2025
Manganese
Detected: 29 UG/L (ppb)
10/7/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Arsenic
Detected: 2.4 UG/L (ppb)
10/28/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Chromium, Hex
Detected: 0.62 UG/L (ppb)
7/22/2025
Barium
Detected: 130 UG/L (ppb)
9/30/2025
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 2.8 UG/L (ppb)
6/24/2025
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.
Bromoform
Detected: 2 UG/L (ppb)
6/24/2025
Dibromochloromethane
Detected: 0.87 UG/L (ppb)

Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Nitrate
Detected: 7.9 MG/L (ppm)
10/7/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
