Some 9.2 million lead pipes carry water into homes across the U.S., with more in Florida than any other state, according to a new Environmental Protection Agency survey that will dictate how billions of dollars to find and replace those pipes are spent. The survey released Tuesday was the first time the agency asked about lead pipes and gave the best count yet of how many are underground. Florida, with an estimated 1.16 million pipes, was a surprise to one expert. Industrial states like Ohio, Michigan and Pennsylvania are more typically associated with extensive lead pipe issues.
