Results for VENTURA, CA

3 water providers on file serving this city.

Quick answer: VENTURA's water has no violation currently counted toward its compliance status. EPA's record shows a Selenium violation dating to 01/01/2025 (1 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.

Lead And Copper Rule Revisions

Currently open health violation

Found at 1 of 3 providers

Selenium

Older/archived health-based violation

Found at 1 of 3 providers

Contaminants found

Metals

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

Lead Summary

Detected: 0 mg/L (ppm)

Found at 3 providers

Copper, Free

Detected: 204 UG/L (ppb)

Found at 2 providers

Iron

Detected: 60 UG/L (ppb)

4/21/2025

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

Manganese

Detected: 115 UG/L (ppb)

4/21/2025

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

Chromium

Detected: 10 UG/L (ppb)

4/21/2025

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

Zinc

Detected: 30 UG/L (ppb)

4/21/2025

Combined Uranium

Detected: 14.7 PCI/L

7/9/2025

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

Selenium

Detected: 47 UG/L (ppb)

7/10/2025

Disinfection Byproducts

Formed when chlorine used to disinfect water reacts with organic matter

Totalhaloaceticacids (HAA5)

Detected: 7 UG/L (ppb)

2/27/2025

TTHM

Detected: 42 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.

Bromoform

Detected: 25 UG/L (ppb)

Found at 2 providers

Bromodichloromethane

Detected: 3 UG/L (ppb)

Found at 2 providers

Dibromochloromethane

Detected: 14 UG/L (ppb)

4/21/2025

Nitrate

Detected: 8.3 MG/L (ppm)

9/3/2025

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

Minerals

Everyday minerals that mainly affect taste and water hardness

Magnesium

Detected: 48 MG/L (ppm)

4/21/2025

Potassium
