Results for ESCALON, CA
1 water provider on file serving this city.
Quick answer: ESCALON's water has no violation currently counted toward its compliance status. EPA's record shows a Nitrate violation dating to 11/01/1984 (42 years ago) — because it's more than five years past its deadline, EPA's policy no longer treats it as part of this system's current standing, though it remains on the public record.

Found at 1 of 1 provider
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Contaminants found
Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper

Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Chromium
Detected: 11 UG/L (ppb)
3/11/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 125 UG/L (ppb)
3/11/2025
Arsenic
Detected: 3 UG/L (ppb)
3/11/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
