Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Manganese
Detected: 10 UG/L (ppb)
10/1/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Arsenic
Detected: 6 UG/L (ppb)
10/15/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Vanadium, Total
Detected: 63 UG/L (ppb)

Iron
Detected: 170 UG/L (ppb)
10/1/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Zinc
Detected: 10 UG/L (ppb)

Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 5 UG/L (ppb)
8/6/2025
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.
