Friday Top of the Scroll: Biden administration proposes big changes to lead pipe rules
Most U.S. cities would have to replace lead water pipes within 10 years under strict new rules proposed by the Environmental Protection Agency as the Biden administration moves to reduce lead in drinking water and prevent public health crises like the ones in Flint, Mich., and Washington, D.C. Millions of people consume drinking water from lead pipes, and the agency said tighter standards would improve IQ scores in children and reduce high blood pressure and heart disease in adults. It would be the biggest overhaul of lead rules in more than three decades and would cost billions of dollars. Pulling it off would require overcoming enormous practical and financial obstacles.
