3 PFAS compounds above EPA limits in Hesperia Wd, CA
The EPA finalized the first-ever federal drinking-water limits for six PFAS compounds in April 2024. These numbers come straight from EPA's UCMR5 lab dataset — every U.S. system serving more than 3,300 people tested every PFAS sample at an entry point to its distribution system. PFAS not listed below were either tested and not detected, or not yet sampled.

+Is Hesperia Wd, CA tap water safe to drink in 2023?
The 2023 Consumer Confidence Report for the Hesperia Wd, CA water utility lists 3 contaminants at or above the federal limit: PFOS, PFOA, and Perfluorohexanesulfonic acid. Whether that means the water is "unsafe" depends on which contaminant, how long the exposure, and individual health factors. The table on this page shows the measured value, the federal threshold, and the regulated statistic used for compliance.
+What contaminants are in Hesperia Wd, CA tap water?
47 contaminants were measured in Hesperia Wd, CA's 2023 Consumer Confidence Report, spanning other, pfas ("forever chemicals"), and disinfection byproducts. 32 have an enforceable federal limit; the rest are detected but unregulated. Every measured value, in the utility's own units, is on this page.
+Which contaminants exceed federal limits in Hesperia Wd, CA tap water?
3 contaminants in Hesperia Wd, CA's 2023 report sit at or above the federal limit: PFOS (2.8× the limit); PFOA (2.6× the limit); Perfluorohexanesulfonic acid (1.1× the limit). The EPA enforces these limits against the regulated reporting statistic — typically a running annual average or 90th percentile — not a one-off sample spike.
+What is the worst contaminant in Hesperia Wd, CA tap water?
The contaminant with the highest measured value relative to its federal limit in the 2023 report is PFOS, at 2.8× the federal threshold. It belongs to the pfas ("forever chemicals") family of contaminants.
+Where does the data on this page come from?
Every value is transcribed from Hesperia Wd, CA's 2023 Consumer Confidence Report — the annual drinking-water report every U.S. public water utility is required by federal law to publish. The original source document is archived and viewable on this site. A water-quality report covers an entire service area, not a single address.
+How often is Hesperia Wd, CA's water quality data updated?
Each U.S. public water utility publishes one Consumer Confidence Report per year, covering the prior calendar year's measurements. This page reflects the 2023 report; a new report will replace it once the utility publishes its next annual update.
