+Is Town of Accident, MD tap water safe to drink in 2024?
The 2024 Consumer Confidence Report for the Town of Accident, MD water utility lists 5 contaminants at or above the federal limit: Hexafluoropropylene oxide dimer acid, Perfluorohexanesulfonic acid, Perfluorononanoic acid, 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 Town of Accident, MD tap water?
16 contaminants were measured in Town of Accident, MD's 2024 Consumer Confidence Report, spanning pfas ("forever chemicals"), metals, and disinfection byproducts. 5 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 Town of Accident, MD tap water?
5 contaminants in Town of Accident, MD's 2024 report sit at or above the federal limit: Hexafluoropropylene oxide dimer acid (1.0× the limit); Perfluorohexanesulfonic acid (1.0× the limit); Perfluorononanoic acid (1.0× the limit); PFOA (1.0× the limit); PFOS (1.0× 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.
