Frequently Asked Questions About Oildale Tap Water
Oildale's water has 4 contaminants above EPA MCLGs. We strongly recommend using a certified water filter to reduce exposure to these contaminants. Check our filter recommendations below for NSF-certified options that can remove the specific contaminants found in Oildale's water. EPA records 5 health-based violations for OILDALE MWC that began after its latest compliance result on file (Feb 2023): Maximum Contaminant Level Violation, Average (TTHM), 2 violations, the first beginning on January 1, 2024 and the latest on April 1, 2024; Maximum Contaminant Level Violation, Average (Total Haloacetic Acids (HAA5)), 3 violations, the first beginning on July 1, 2023 and the latest on January 1, 2024. Every such result predates them; its later EPA UCMR 5 results (Nov 2023) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
