Abstract
Concerns about drinking water contamination through lead service lines may hinder resource-constrained municipalities from performing important infrastructure upgrades. Construction on water mains may shake the service lines and increase lead levels in drinking water. We estimate the effects of water main maintenance on drinking water and children’s blood levels exploiting over 2,500 water main replacements in Chicagoa city with almost 400,000 lead service linesand unique geocoded data. By comparing tests in homes at different distances from replaced mains before and after replacementwe find no evidence that water main replacement affects water or children’s lead levels.
