US lawmakers call for more measures to protect against toxic lead in tap water

Senators make appeal to EPA after series of Guardian articles revealed that communities of color often face high lead levels

US legislators are calling for increased measures to protect American residents from toxic lead in their tap water.

A group of up to 15 US senators asked the Environmental Protection Agency on Tuesday to lower the levels of lead allowable in drinking water, require all lead pipes to be replaced in the next decade and ensure that low-income neighborhoods can benefit equally from the remediation efforts.
