Contaminants found
Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0.0022 mg/L (ppm)
12/31/2025
Combined Uranium
Detected: 3.63 PCI/L
9/2/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Iron
Detected: 27 UG/L (ppb)
10/6/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 43 UG/L (ppb)
10/6/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
