Lead Summary
Detected: 0 mg/L (ppm)
12/31/2024
Vanadium, Total
Detected: 19 UG/L (ppb)

Chromium, Hex
Detected: 13 UG/L (ppb)
8/13/2025
Combined Uranium
Detected: 4.6 PCI/L
4/2/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Iron
Detected: 110 UG/L (ppb)
10/13/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Nickel
Detected: 11 UG/L (ppb)
3/4/2025
Chromium
Detected: 16 UG/L (ppb)
10/13/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 120 UG/L (ppb)
10/13/2025
Arsenic
Detected: 3.2 UG/L (ppb)
10/13/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Selenium
Detected: 5.1 UG/L (ppb)
10/13/2025
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Totalhaloaceticacids (HAA5)
Detected: 13.6 UG/L (ppb)

TTHM
Detected: 50.5 UG/L (ppb)
10/8/2025
A group of disinfection byproducts formed when chlorine reacts with organic matter. Long-term exposure above the legal limit has been linked to increased cancer risk in some studies.
Bromoform
Detected: 12.1 UG/L (ppb)
10/8/2025
Dibromochloromethane
Detected: 19.4 UG/L (ppb)
10/8/2025
