Frequently asked
+What is Beryllium?
Beryllium is a contaminant some U.S. public water utilities measure and report in their annual Consumer Confidence Report.
+What is the federal limit for Beryllium in drinking water?
The federal MCL for Beryllium is 0.004 mg/L. The EPA enforces this against the regulated reporting statistic (typically a running annual average or 90th percentile), not a single-sample spike.
+How many U.S. water systems have Beryllium over the federal limit?
Zero of the 51 public water systems in The Water Map dataset currently report Beryllium at or above its federal limit.
+How can I check if Beryllium 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 Beryllium.
