Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Lead
Detected: 12 UG/L (ppb)
9/16/2025
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: 180 UG/L (ppb)
9/16/2025
Arsenic
Detected: 7.8 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.
Iron
Detected: 600 UG/L (ppb)
2/19/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium, Hex
Detected: 2.4 UG/L (ppb)
4/23/2025
Barium
Detected: 110 UG/L (ppb)
2/6/2025
Selenium
Detected: 7.7 UG/L (ppb)
2/6/2025
Aluminum
Detected: 270 UG/L (ppb)

Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Nitrate
Detected: 1 MG/L (ppm)
10/7/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Chloride
Detected: 270 MG/L (ppm)
2/6/2025
Fluoride
Detected: 0.27 MG/L (ppm)
2/6/2025
Often added deliberately for dental health; can also occur naturally.
Nitrate-Nitrite
Detected: 0.76 MG/L (ppm)
