Why is it so unusually expensive to replace lead pipes in Chicago?

Chicago, home to the highest number of lead pipes in the U.S., is facing an unexpectedly high cost for replacing these hazardous materials, far exceeding national averages. While the exact reasons behind this surge in expense remain unclear, officials suspect factors like complex infrastructure and the need for specialized contractors. This situation underscores broader issues in urban infrastructure maintenance, highlighting the financial and health risks tied to aging water systems and the challenges of comprehensive public health initiatives. The implications extend beyond Chicago, raising questions about nationwide water safety and the economic burden on communities dealing with similar issues.
