+What is the federal limit for Aluminum in drinking water?

The federal Public health goal for Aluminum is 600 ug/L. The EPA enforces this against the regulated reporting statistic (typically a running annual average or 90th percentile), not a single-sample spike.

Zero of the 485 public water systems in The Water Map dataset currently report Aluminum at or above its federal limit.

+How can I check if Aluminum is in my city's tap water?

Search your city on The Water Map (https://www.thewatermap.com/) or browse the list on this page. Every U.S. public water utility is required to publish an annual Consumer Confidence Report that lists every contaminant it measured, including Aluminum.
