Violations on file

Selenium

Older/archived health-based violation

Found at 4 of 167 providers

Nitrate

Older/archived health-based violation

Found at 13 of 167 providers

Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.

Fluoride

Older/archived health-based violation

Found at 1 of 167 providers

Often added deliberately for dental health; can also occur naturally.

Lead And Copper Rule Revisions

Currently open health violation

Found at 3 of 167 providers

Contaminants found

Metals

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

Lead Summary

Detected: 0.0205 mg/L (ppm)

Found at 57 providers

Copper Summary

Detected: 2.215 mg/L (ppm)

Found at 3 providers

Copper, Free

Detected: 190 UG/L (ppb)

Found at 13 providers

Combined Uranium

Detected: 15.7 PCI/L

Found at 14 providers

Arsenic

Detected: 8.4 UG/L (ppb)

Found at 13 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.
