People also ask about Edison, NJ's water
+Is Edison, NJ tap water safe to drink in 2024?
The 2024 Consumer Confidence Report for the Edison, NJ water utility lists 2 contaminants at or above the federal limit: PFOA and PFOS. 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 Edison, NJ tap water?
32 contaminants were measured in Edison, NJ's 2024 Consumer Confidence Report, spanning metals, pfas ("forever chemicals"), and disinfection byproducts. 9 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 Edison, NJ tap water?
2 contaminants in Edison, NJ's 2024 report sit at or above the federal limit: PFOA (1.5× the limit); PFOS (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 Edison, NJ tap water?
The contaminant with the highest measured value relative to its federal limit in the 2024 report is PFOA, at 1.5× the federal threshold. It belongs to the pfas ("forever chemicals") family of contaminants.
+Are any contaminants in Edison, NJ tap water approaching the federal limit?
One contaminant is between 80% and 100% of the federal limit in this report: Bromate. Approaching means measured but not in violation — a margin that can close quickly if conditions change.
+Where does the data on this page come from?
Every value is transcribed from Edison, NJ'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 Edison, NJ'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.
