The Oak Ridge Reservation is situated in East Tennessee, in and adjacent to the city of Oak Ridge. The U.S. Department of Energy (DOE) operates three sites on the reservation: the East Tennessee Technology Park (formerly the K-25 Site), Oak Ridge National Laboratory, and the Y-12 National Security Complex. The three sites are government-owned, contractor-operated facilities; under DOE guidance, private companies manage the day-to-day operations of the sites according to federal laws, DOE orders, and state laws and regulations.

Government-sponsored activities on the reservation date back to the Manhattan Project and continue to the current day. Both past and current activities involve hazardous chemicals and radioactive materials. The DOE requires that an annual report be published to describe the effect that these activities have on the reservation and its surroundings. Data for the report are gathered by effluent monitoring (collection and analysis of samples of various media prior to contaminant release) and environmental surveillance (sampling of various media to obtain direct measurements subsequent to contaminant release).
