"The Biden administration announced on Wednesday that it is delaying the implementation of a Trump administration update to a rule governing lead and copper in drinking water.
The rule in question is expected to quicken the speed at which cities need to notify people who may have been exposed to lead but gives utilities a longer timeline to replace lead-tainted service lines.
A new statement from the Environmental Protection Agency (EPA) said that it is extending the date that the rule becomes effective, delaying it until at least June 17. It was originally expected to go into effect next week."
