Zinc
Detected: 160 UG/L (ppb)
7/30/2025
Iron
Detected: 100 UG/L (ppb)
6/13/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Arsenic
Detected: 2 UG/L (ppb)
6/13/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Aluminum
Detected: 68 UG/L (ppb)
