Environmental Surveillance and Oversight Program Overview, In 1995, South Carolina Department of Health and Environmental Control (now the South Carolina Department of Environmental Services, SCDES) enrolled in an Agreement in Principle (AIP) program with the U.S. Department of Energy –SRS (DOE-SR). As a result of this agreement, the Environmental Surveillance and Oversight Program (ESOP) was created in SCDES’s Midlands Aiken Environmental Affairs…, air, , , groundwater, , , drinking water,, , surface water, ,, , soil and sediment, , , milk, , , vegetation,, and , fish and game, for the presence of radiological and non-radiological chemicals. Each year we conduct a critical pathway/dose assessment to calculate the potential exposure or dose to the public within 50 miles of the center of the SRS., Annual Reports and Outreach, In pursuit of SCDES’s mission of promoting and protecting the health of the people and the environment, ESOP is committed to educating the public of its findings. ESOP publishes an annual report providing the results of its studies, comparisons with DOE-SR’s data, and a calculated dose. The most current report can be found below, and past results can be found under the, Monitoring Data & Sampling Locations, Maps, heading. Along with publications, ESOP’s efforts and results are also provided to the public through presentations and hands-on demonstrations at SRS Citizen Advisory Board (CAB) meetings, local community groups, Aiken County schools and career fairs, USC Aiken’s Science Enrichment and Education Day (SEED), and local Earth Day celebrations.
