Lead Summary
Detected: 0 mg/L (ppm)
12/31/2023
Manganese
Detected: 37 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: 11 UG/L (ppb)
10/9/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium, Hex
Detected: 0.68 UG/L (ppb)
1/6/2025
Chromium
Detected: 1.3 UG/L (ppb)
4/2/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Totalhaloaceticacids (HAA5)
Detected: 6.5 UG/L (ppb)
10/15/2025
TTHM
Detected: 25 UG/L (ppb)
10/15/2025
