The study area is located on a portion of a former 17-acre cooling water pond. It was used from October 1951 to April 1954 to receive process vessel cooling water and steam condensate arising from operation of the Redox plant. The pond was taken out of service when an inadvertent release of fission products caused the radionuclide concentrations in the pond sediments to exceed prescribed disposal limits. At that time the pipeline to the pond was plugged and the pond allowed to dry out. The pond was covered with non-contaminated soil fill to prevent the spread of contamination by wind. Russian thistles and bursage became self-established in the area and their roots penetrated to the contaminated area. The fall of 1974 additional soil fill was added and 0.9 ha of this clean soil fill was used to establish a revegetation test area. The soil fill was wetted and compacted to reduce erosion and settling and to provide a moist environment to encourage seed germination. Four soil treatments were chosen for the experiment: a control, and soil amendments of bentonite clay, straw, and a straw/clay mixture. The degree of success of revegetation of various species under the different conditions is discussed.
