The City of Flint says it needs more time to submit water tests from homes at highest risk for having lead water lines.
Under the state and federal Lead and Copper Rule, Flint has to test for lead more often than other cities because of the water crisis.
The city says it must test 60 homes with lead lines, every six months.
Flint has tested more than 60 sites but, so far, believes they’ve only confirmed 43 of those lead water lines. The city says it needs more time to determine if the rest of its tests fit the criteria.
Flint has also proactively asked for an extension to submit test results for the time period ending June 30, 2020.
The problem is Flint has exceptionally poor or nonexistent records for what kind of water pipes hook up to people's homes, and it has already dug up thousands of lines and replaced those that had lead.
The good news is, by July, the city thinks it will have replaced all of the lead lines that remain.
Meanwhile, since 2017, Flint's water has tested below the federal action level for lead in drinking water.
