Lead Summary
Detected: 0 mg/L (ppm)
12/31/2025
Combined Uranium
Detected: 17 PCI/L
10/6/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 2.6 UG/L (ppb)
10/6/2025
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.
Totalhaloaceticacids (HAA5)
Detected: 3.3 UG/L (ppb)
10/6/2025
Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Fluoride
Detected: 1 MG/L (ppm)
11/3/2025
Often added deliberately for dental health; can also occur naturally.
Nitrate
Detected: 5 MG/L (ppm)
10/6/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
