Frequent Questions

Is the EPA currently considering putting a limit on how much chromium-6 can be in drinking water?

EPA currently regulates chromium-6 as part of the total chromium drinking water standard. New health effects information has become available since the original standard was set, and EPA is reviewing this information to determine whether there are new health risks that need to be addressed. When the review is complete, we will consider this and other information to decide whether the drinking water standard for total chromium needs to be updated.
