PFAS — EPA UCMR5 (2023–2025)
2 PFAS compounds above EPA limits in High Point, NC
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.

People also ask about High Point, NC's water
+Is High Point, NC tap water safe to drink in 2024?
The 2024 Consumer Confidence Report for the High Point, NC water utility lists 3 contaminants at or above the federal limit: PFOS, TTHM, and HAA5. 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 High Point, NC tap water?
84 contaminants were measured in High Point, NC's 2024 Consumer Confidence Report, spanning other, metals, and vocs & pesticides. 37 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 High Point, NC tap water?
3 contaminants in High Point, NC's 2024 report sit at or above the federal limit: PFOS (2.3× the limit); TTHM (1.4× the limit); HAA5 (1.3× 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 High Point, NC tap water?
The contaminant with the highest measured value relative to its federal limit in the 2024 report is PFOS, at 2.3× 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 High Point, NC's 2024 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 High Point, NC'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 2024 report; a new report will replace it once the utility publishes its next annual update.
