Can US pull off a $30bn plan to dump lead water pipes?

President Joe Biden's administration has announced a plan to rip out nine million lead water pipes across the US.

The 10-year proposal aims to shield communities from a neurotoxin that can cause permanent damage to the brain and nervous system, especially in children.

It would cost about $30bn (£24bn), the Environmental Protection Agency says.

The task is no small feat, but is a "really big step for the US", Rutgers University Professor Douglas Cantor tells the BBC.

He says it is a lofty goal, though "totally doable".
