This archived EPA consumer fact sheet restates the drinking-water goal and the enforceable maximum for antimony in parts per billion. The document is on the EPA archive site. Its long-term health paragraph is an unfilled template. That paragraph is not quoted on this page.
Key numbers
The text prints that the MCLG for antimony has been set at 6 parts per billion (ppb), and that the MCL has also been set at 6 ppb (PDF p.2). A summary box prints MCLG: 6 ppb and MCL: 6 ppb (PDF p.3). Monitoring language says the supplier was to determine whether antimony is present above 6 ppb. Approved removal methods printed here are coagulation and filtration, and reverse osmosis. The regulation is described as having become effective in 1994.
The short-term health sentence is filled and names nausea, vomiting, and diarrhea above the MCL for relatively short periods. The long-term health paragraph stops in an unfilled template. It is not transcribed.
Methods (brief)
The file is the archived consumer fact sheet PDF. It points readers to the National Primary Drinking Water Regulations. It is not the CFR text.
Evidence fitness
The page supports the archived sheet’s own statement of 6 ppb for both the goal and the maximum, which matches 0.006 mg/L in the CFR sections opened with it. It does not support quotation of the unfilled long-term health paragraph. It does not support a diaper limit or a textile limit.
Limitations
The sheet is archived and was not updated to the 2025 CFR edition. Release totals and production figures printed on the sheet are not drinking-water limits and are not adopted here as occurrence data.
