10/8/2025
Iron
Detected: 300 UG/L (ppb)
10/8/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 21 UG/L (ppb)
10/8/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.

Nickel
Detected: 2 UG/L (ppb)
10/8/2025
Chromium
Detected: 0.94 UG/L (ppb)
7/8/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 34 UG/L (ppb)
10/8/2025
Arsenic
Detected: 2.7 UG/L (ppb)
10/8/2025

10/14/2025
TTHM
Detected: 74 UG/L (ppb)
10/14/2025
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.
