Combined Uranium
Detected: 4.1 PCI/L
10/14/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Vanadium, Total
Detected: 9.1 UG/L (ppb)

Detected: 4.4 UG/L (ppb)
10/14/2025
Arsenic
Detected: 5.1 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.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 1.6 UG/L (ppb)
9/2/2025
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.
