Lead Summary
Detected: 0.0029 mg/L (ppm)
Found at 4 providers
Lead
Detected: 5.7 UG/L (ppb)
Found at 2 providers
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.
Copper, Free
Detected: 80 UG/L (ppb)
Found at 2 providers
Chromium, Hex
Detected: 4.9 UG/L (ppb)
Found at 2 providers
Arsenic
Detected: 8.7 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.
Combined Uranium
Detected: 2.8 PCI/L
8/22/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.

Detected: 8.9 UG/L (ppb)
8/12/2025
TTHM
Detected: 62.6 UG/L (ppb)
Found at 2 providers
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.
Chloroform
Detected: 54.3 UG/L (ppb)
Found at 2 providers
One of the individual trihalomethane disinfection byproducts, formed when chlorine reacts with organic matter.
