Lead Summary
Detected: 0 mg/L (ppm)
12/31/2024
Combined Uranium
Detected: 9.1 PCI/L
9/9/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Arsenic
Detected: 2.7 UG/L (ppb)
10/1/2025
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: 62 UG/L (ppb)
4/29/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium, Hex
Detected: 1.9 UG/L (ppb)
