Biological surveys on the Savannah River in the vicinity of the Savannah River Plant (1951-1976)

Description: In 1951, the Academy of Natural Sciences of Philadelphia was contracted by the Savannah River Plant to initiate a long-term monitoring program in the Savannah River. The purpose of this program was to determine the effect of the Savannah River Plant on the Savannah River aquatic ecosystem. The data from this monitoring program have been computerized by the Savannah River Laboratory, and are summarized in this report. During the period from 1951-1976, 16 major surveys were conducted by the Academy in the Savannah River. Water chemistry analyses were made, and all major biological communities were sampled qualitatively during the spring and fall of each survey year. In addition, quantitative diatom data have been collected quarterly since 1953. Major changes in the Savannah River basin, in the Savannah River Plant's activities, and in the Academy sampling patterns are discussed to provide a historical overview of the biomonitoring program. Appendices include a complete taxonomic listing of species collected from the Savannah River, and summaries of the entire biological and physicochemical data base.

Distribution of polychlorinated biphenyls (PCBs) in surface sediments of Gable Mountain Pond

Description: Samples of sediments were collected and analyzed to determine the concentration and distribution of polychlorinated biphenyls (PCBs) in Gable Mountain Pond, which is located on the Hanford Site in southeastern Washington State. All samples, with one exception, were found to contain the specific PCB Aroclor 1260, a constituent of the insulating fluid used in electric utility transformers. The highest concentration of PCBs in the pond was found next to the mouth of the inlet pipe. The distribution of PCBs over the pond is consistent with the hypothesis that they entered primarily through the inlet pipe and spread along the length of the pond in a roughly westerly direction. Concentrations of Arochlor 1260 ranged from 2 to 148 parts per billion, which is roughly two to four orders of magnitude below the regulated upper concentration limit (50 parts per million) for the disposal of PCB-contaminated waste. 19 res., 8 figs., 2 tabs.
