Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Lead
Detected: 1 UG/L (ppb)
8/26/2025
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: 446 UG/L (ppb)
9/19/2025
Chromium, Hex
Detected: 6.1 UG/L (ppb)
10/20/2025
Arsenic
Detected: 3 UG/L (ppb)
9/15/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Iron
Detected: 160 UG/L (ppb)
4/2/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium
Detected: 12 UG/L (ppb)
6/4/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Nitrate
Detected: 1.1 MG/L (ppm)
10/20/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Sulfate
