Biodegradation of uranium-containing waste oils and degreaser sludge in soil

Technical Report ·
OSTI ID:6259989
The potential for biodegradation by landfarming of uranium-containing waste oils and degreaser sludge from Goodyear Atomic's Piketon, Ohio operation was evaluated. Biodegradation in GAT soil was monitored in soil respirometer flasks, which are small glass vessels which permit monitoring the evolution of carbon dioxide from soils which received waste oil or degreaser sludge. Oils and sludges were added to soil at three different rates of application, based on previous work reported in the scientific literature. In addition, some treatments received fertilizer nitrogen and phosphorus, at specific ratios based on evaluation of the scientific literature. Other parameters, such as soil moisture, aeration, and pH were optimized for microbial degradation. Results of the biodegradation experiments were used in a technico-economic evaluation of the feasibility of landfarming waste oils and degreaser sludge either in an open system, enclosed in a glass greenhouse, or in an air-supported greenhouse. 42 refs., 22 figs., 8 tabs.
