Results for LINDSAY, CA
3 water providers on file serving this city.
Quick answer: LINDSAY's water has no violation currently counted toward its compliance status. EPA's record shows a Total Haloacetic Acids (HAA5) violation dating to 10/01/2022 (4 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.

Violations on file
Total Haloacetic Acids (HAA5)
Older/archived health-based violation
Found at 1 of 3 providers
TTHM
Older/archived health-based violation
Found at 1 of 3 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.
Contaminants found
Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0 mg/L (ppm)
12/31/2024
Iron
Detected: 89 UG/L (ppb)
7/7/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Arsenic
Detected: 2.2 UG/L (ppb)
7/7/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
