Lead Summary
Detected: 0 mg/L (ppm)
12/31/2023
Lead
Detected: 20 UG/L (ppb)
8/14/2025
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.
Chromium, Hex
Detected: 3.6 UG/L (ppb)

Barium
Detected: 61 UG/L (ppb)
10/9/2025
Arsenic
Detected: 2.1 UG/L (ppb)
8/14/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
