"Water departments that use controversial lead-testing practices have told the Guardian they will change their methods after an investigation revealed they were not following environmental guidelines.
Most of the water departments involved said they used the testing methods because state governments told them to, federal guidance was not clear, or they had not received any word that practices may underestimate lead content.
The investigation into lead testing methods comes after the lead contamination crisis in Flint, Michigan, where indictments against three government officials referenced water testing methods as part of an alleged coverup."
