WASHINGTON - An ongoing process to replace lead water pipes in Washington, D.C., reveals several warning signs for the Baltimore area as officials here check more than 275,000 pipes for lead.

Since 2019, D.C. officials have replaced 5,400 lead pipes mostly for free to customers — but it comes at a cost amid an uncertain future. Federal funding is set to run out and there will be more lead pipes than expected that need to be replaced at a cost of almost $2 billion.
