Contaminants found

Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0.0054 mg/L (ppm)
12/31/2025
Iron
Detected: 67 UG/L (ppb)
8/20/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 47 UG/L (ppb)
8/20/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Totalhaloaceticacids (HAA5)
Detected: 11 UG/L (ppb)
1/15/2025
TTHM
Detected: 42 UG/L (ppb)
1/15/2025
