Lead Summary
Detected: 0 mg/L (ppm)
12/31/2023
Manganese
Detected: 97 UG/L (ppb)
10/9/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Iron
Detected: 46 UG/L (ppb)
5/15/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter

Detected: 1 UG/L (ppb)
2/4/2025
TTHM
Detected: 1.4 UG/L (ppb)
