The Biden administration has announced a proposal to “strengthen its Lead and Copper Rule that would require water systems to replace lead service lines within 10 years,” the White House said in a statement on Thursday.

According to the White House, more than 9.2 million American households connect to water through lead pipes and lead service lines and, due to “decades of inequitable infrastructure development and underinvestment,” many Americans are at risk of lead exposure.

“There is no safe level of exposure to lead, particularly for children, and eliminating lead exposure from the air, water, and homes is a crucial component of the Biden-Harris Administration’s historic commitment to advancing environmental justice,” the Biden administration said.
