CITY OF SANGER (SANGER, CA), which serves about 26,357 people, has recorded 2 health-based drinking-water contaminants in EPA violation records since 2016, most notably Copper, Lead. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFOS (0.0067 µg/L), PFOA (0.0056 µg/L), PFPeA (0.0051 µg/L). PFOA/PFOS levels exceed the 2024 federal limit of 4 ppt (0.004 µg/L). A certified water filter can reduce these at the tap — see the certified options for each below.
What the testing found
Measured levels from EPA violation records, compared to the federal limit (MCL). The black line marks the legal limit.

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
