As other cities dig up pipes made of toxic lead, Chicago resists

As cities across the nation overhaul their aging, increasingly fragile drinking water systems, some municipal leaders are digging deeper to erase a toxic legacy that endangers millions of Americans: lead water pipes connecting homes to street mains.

The growing list includes Milwaukee, Boston, Philadelphia, Pittsburgh, Denver and St. Paul, all of which are adding pipe replacements to municipal construction projects by dipping into local funds, offering homeowners payment plans or taking advantage of low-interest loans funded jointly by federal and state lawmakers. Other cities have plans in the works.
