The mission of Crowd the Tap is to ensure safe drinking water in the United States. Make your home part of the national inventory of water pipe materials! The inventory will help prioritize areas for tap water testing and infrastructure replacement. Being part of the inventory will connect you with others in your neighborhood and beyond who want to make drinking water safe for all.
