Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0 mg/L (ppm)
12/31/2024
Combined Uranium
Detected: 6.3 PCI/L
8/26/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Chromium, Hex
Detected: 15 UG/L (ppb)
8/19/2025
Chromium
Detected: 14 UG/L (ppb)
8/19/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 37 UG/L (ppb)
8/26/2025
Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
