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.
That data is still from 2009 though, but sadly there doesn’t seem to be a newer statistic. Since that time many changes were made to push for the removal of old lead piping in the EU.
Anyway the threshold for lead in drinking water in the EU is 10ug/L since 2013.
Since 2020 a regulation has been in effect with the goal to have less than 5 ug/L drinking water at the consumer until 2036 everywhere in the EU.

The US has a threshold of 15 ug/L.
