A new federal rule will require water utilities across the country to pull millions of lead drinking water pipes out of the ground and replace them, at a cost of billions of dollars. States, cities and water utilities agree that the lead pipes need to go to ensure safe water for residents. But they say they may struggle to do so in the 10-year window required under the rule, and they fear some ratepayers will be hit with massive cost increases to pay for the work. State officials are urging Congress to provide ongoing funding for the lead replacement effort. Local leaders say they’ll need lots of help to meet the deadline. And environmental advocates are calling on states to issue bonds or provide other financial support to water utilities.
