Requires the head of each federal agency to conduct water supply testing in federally-owned or occupied buildings.

Directs each water system to test drinking water for lead contamination within one year.

Prohibits the use of lead pipes and plumbing equipment that is not lead free in public water systems or facilities that provide drinking water.
