Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Combined Uranium
Detected: 1.9 PCI/L
2/25/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Chromium, Hex
Detected: 0.37 UG/L (ppb)
5/6/2025
Barium
Detected: 130 UG/L (ppb)
5/13/2025
Arsenic
Detected: 6.4 UG/L (ppb)
10/7/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Copper, Free
Detected: 490 UG/L (ppb)
9/10/2025
Iron
Detected: 37 UG/L (ppb)
10/9/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 13 UG/L (ppb)
10/9/2025
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
Nitrate
Detected: 1 MG/L (ppm)
8/13/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Fluoride
Detected: 0.48 MG/L (ppm)
10/14/2025
Often added deliberately for dental health; can also occur naturally.
Chloride
Detected: 2.4 MG/L (ppm)
8/13/2025
Sulfate
Detected: 3.1 MG/L (ppm)
