Contaminants found

Metals

Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper

Lead Summary

Detected: 0.0414 mg/L (ppm)

Found at 44 providers

Chromium, Hex

Detected: 2.7 UG/L (ppb)

Found at 12 providers

Iron

Detected: 8710 UG/L (ppb)

Found at 7 providers

Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.

Manganese

Detected: 367 UG/L (ppb)

Found at 6 providers

Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.

Arsenic

Detected: 39 UG/L (ppb)

Found at 7 providers

Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.

Copper Summary

Detected: 203 mg/L (ppm)

Found at 3 providers

Aluminum

Detected: 95 UG/L (ppb)

Found at 3 providers

Combined Uranium

Detected: 1.18 PCI/L

Found at 2 providers

A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.

Lead

Detected: 1.4 UG/L (ppb)

Found at 4 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: 1220 UG/L (ppb)

Found at 4 providers

Chromium

Detected: 2 UG/L (ppb)

7/9/2025

Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).

Barium

Detected: 98 UG/L (ppb)

Found at 2 providers

Disinfection Byproducts

Formed when chlorine used to disinfect water reacts with organic matter

TTHM

Detected: 73.2 UG/L (ppb)

Found at 14 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.

Found at 13 providers

Dibromochloromethane

Detected: 4.6 UG/L (ppb)

Found at 5 providers
