+Is Hialeah, FL tap water safe to drink in 2023?
The 2023 Consumer Confidence Report for the Hialeah, FL water utility lists 6 contaminants at or above the federal limit: PFOS, PFOA, Thallium, Dehp, HAA5, and Chloramine. 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 Hialeah, FL tap water?
25 contaminants were measured in Hialeah, FL's 2023 Consumer Confidence Report, spanning metals, radionuclides, and inorganic chemicals. 10 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 Hialeah, FL tap water?
6 contaminants in Hialeah, FL's 2023 report sit at or above the federal limit: PFOS (9.5× the limit); PFOA (7.5× the limit); Thallium (4.5× the limit); Dehp (3.2× the limit); HAA5 (1.6× the limit); Chloramine (1.5× 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 Hialeah, FL tap water?
The contaminant with the highest measured value relative to its federal limit in the 2023 report is PFOS, at 9.5× the federal threshold. It belongs to the pfas ("forever chemicals") family of contaminants.
