A decade after the Flint, Michigan, water crisis raised alarms about the continuing dangers of lead in tap water, President Joe Biden is setting a 10-year deadline for cities across the nation to replace their lead pipes, finalizing an aggressive approach aimed at ensuring that drinking water is safe for all Americans.
Biden is expected to announce the final Environmental Protection Agency rule Tuesday in the swing state of Wisconsin during the final month of a tight presidential campaign. The announcement highlights an issue — safe drinking water — that Kamala Harris has prioritized as vice president and during her presidential campaign. The new rule supplants a looser standard set by former President Donald Trump’s administration that did not include a universal requirement to replace lead pipes.
Biden and Harris believe it’s “a moral imperative” to ensure that everyone has access to clean drinking water, EPA Administrator Michael Regan told reporters Monday. “We know that over 9 million legacy lead pipes continue to deliver water to homes across our country. But the science has been clear for decades: There is no safe level of lead in our drinking water.’’

You’ll notice that it says “to keep using” lead in plumbing and like applications, and that the early date cited for corporate pushback against health concerns for lead is 1923. Both of those back my assertion that the root cause of lead pipes is their traditional use, and that only relatively recently did health concerns over lead become major.
