Frequently asked

+What is Benzene?

Benzene is a contaminant some U.S. public water utilities measure and report in their annual Consumer Confidence Report.

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

The federal MCLG for Benzene is 0 ug/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 Benzene over the federal limit?

1 of the 45 public water systems on The Water Map report Benzene at or above its federal limit, spanning 8 U.S. states. The full list is on this page.

+How can I check if Benzene 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 Benzene.
