Combined Uranium
Detected: 2 PCI/L
5/1/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Manganese
Detected: 17 UG/L (ppb)
1/27/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Chromium, Hex

Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 1.4 UG/L (ppb)
10/14/2025
