Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0 mg/L (ppm)

Chromium, Hex
Detected: 16 UG/L (ppb)
9/25/2025
Chromium
Detected: 11 UG/L (ppb)
2/19/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 10 UG/L (ppb)
2/3/2025
Arsenic
Detected: 3.4 UG/L (ppb)
2/19/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
TTHM
Detected: 4.1 UG/L (ppb)
9/24/2025
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.
Chloroform
Detected: 0.59 UG/L (ppb)
