Pond B at Savannah River Site is a monomictic reservoir that has received SRS R reactor cooling water from 1961-1964. We're re-evaluating the influence of anthropogenic radionuclides Pu-239 and Cs-137 along with total organic carbon, iron, and trace element in Pond B's contaminated sediments at the Savannah River Site, about 30 years since publication of the last edition on Pond B.

Multiple years of groundwater radioiodine concentration in a riparian wetland located in South Carolina, USA, showed significant seasonal change, such that summer concentrations were much higher than winter concentrations. During the summer, the water table decreased by as much as 0. 7 m, surface water temperature increased by as much as 15 u00b0C, and total iodine concentrations were consistently higher than those months preceding winter months. The observed iodine seasonal variations were also likely to blame for the increased iodine concentrations from the low levels in summer, but the wells intercepted more of the contaminant plume and less of the diluting rainwater and streamwater in summer.

Pond B at Savannah River Site, a monomictic reservoir that received SRS R reactor cooling water from 1961-1964. Past studies, conducted between the 1980s-1990s and the sediments of Pond B found trace amounts of Pu, 241Am, and 137Cs. We are re-evaluating the geochemistry and radionuclide delivery within Pond B at five locations along a horizontal transect from inlet to outlet, about 30 years since the last publication on Pond B.
