Lead Summary
Detected: 0.001 mg/L (ppm)
12/31/2025
Arsenic
Detected: 6.1 UG/L (ppb)
10/28/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Combined Uranium
Detected: 8.2 PCI/L
7/2/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Chromium, Hex
Detected: 12 UG/L (ppb)
10/8/2025
Lead
Detected: 2 UG/L (ppb)
9/17/2025
A metal that can leach from old pipes, solder, and fixtures. Current medical guidance holds there is no truly safe level of lead exposure, especially for children and pregnant women.
Copper, Free
Detected: 44 UG/L (ppb)
9/24/2025
Iron
Detected: 180 UG/L (ppb)
10/28/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 250 UG/L (ppb)
10/28/2025
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
Fluoride
Detected: 0.12 MG/L (ppm)
7/9/2025
Often added deliberately for dental health; can also occur naturally.
Nitrate
Detected: 2.42 MG/L (ppm)
7/24/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Properties
General water characteristics like pH, hardness, and cloudiness (turbidity)
