Puerto Rico suffers the worst rate of drinking water violations of any state or territory in the nation. In 2015, 99.5 percent of Puerto Rico’s population was served by community water systems in violation of the Safe Drinking Water Act, and 69.4 percent of people on the island were served by water sources that violated SDWA’s health standards. The data contained in this report reflect significant drinking water violations in Puerto Rico. These numbers are based on Safe Drinking Water Information System (SDWIS) data reported by the Puerto Rico Department of Health to the U.S. Environmental Protection Agency (EPA).
