U.S. Environmental Protection Agency (USEPA)

The Federal Safe Drinking Water Act of 1974 established the U.S. Environmental Protection Agency (EPA) to be responsible for drinking water standards and monitoring public water utilities. The EPA determines contaminating substances and their potential health effects. They also establish legal health limits and intervene when the states fail to support the limits.

View the EPA's Guide to the Safe Drinking Water Act Poster (PDF, 1.4 Mb).

United States Geological Survey

The United States Geological Survey (USGS) conducts monitoring, assessment and research activities to help understand and protect the quality of our drinking water resources. The USGS website contains reports on MTBE, endocrine disrupters, pesticides, VOCs, disinfection by-products and the latest findings on prescription drugs polluting our drinking water. In particular, their findings of arsenic contamination in ground water are especially concerning.

National Resources Defense Council

Scientists estimate that each year up to seven million Americans become sick from contaminated tap water, which can also be lethal. The National Resources Defense Council (NRDC) safeguards our drinking water by helping to ensure that the Safe Drinking Water Act is carried out effectively, by pushing for citizens' rights to know about contaminants in their water and by conducting scientific research and public education.
