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.
I assume you can test the water at the outlet for lead.
Most of the time these pipes are not actually leeching lead into the water supply. Most of the time. The whole problem is kind of that it happens just often enough, and just locally enough that monitoring doesn’t catch it immediately.
The water authority where I live makes a point of saying they keep the water on the alkaline side to prevent leaching lead from pipes and solder. Presumably that costs money
They must know where at least some of them are so I guess they can start with those and work outwards on the connection. After all I lead the pipe is likely connected to another lead pipe.
Then I guess it’s just a matter of doing a lot of water monitoring for the remaining pipes.
Nope, you have to use historic records or dig holes in the ground. Lead Service Line Inventory projects can take a while, and many cities are already going as fast as they can.
