Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Combined Uranium
Detected: 0.73 PCI/L
8/12/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Iron
Detected: 31 UG/L (ppb)
7/15/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium, Hex
Detected: 8.2 UG/L (ppb)
8/19/2025
Barium
Detected: 97 UG/L (ppb)
8/12/2025
Arsenic
Detected: 2.7 UG/L (ppb)
7/1/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Aluminum
Detected: 83 UG/L (ppb)
8/12/2025
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 3.4 UG/L (ppb)
8/12/2025
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.
Chloroform
Detected: 3.4 UG/L (ppb)
8/12/2025
One of the individual trihalomethane disinfection byproducts, formed when chlorine reacts with organic matter.
