Leaders in Reducing Lead in Drinking Water

EPA remains committed to protecting children from the lifetime impacts of lead.  A top priority for EPA is to work with states and communities to modernize the outdated water infrastructure on which the American public depends on and may be a source of lead in drinking water. This interactive website allows you to explore communities across the country and learn about their programs to reduce lead in drinking water systems.
