Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 24 UG/L (ppb)
9/11/2025

10/8/2025
TTHM
Detected: 17.3 UG/L (ppb)
10/8/2025
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.
