It will then <br /> be thoroughly detoxified using aerobic biodegradation <br /> technology in concordance with the principles described in <br /> the Bioremediation Overview enclosed as Appendix A. Due to <br /> the limited space available for ex-situ treatment , it <br /> appears that the most appropriate technology for use at the <br /> site will be "Forced Air Composting". Contaminated soil <br /> will be placed atop bermed, 6-mil polyethylene sheeting to <br /> a height of approximately 2. 5 feet after being mixed with <br /> mushroom compost , nutrients , and soil amendments to adjust <br /> the chemical and physical characteristics of the soil in a <br /> manner that will encourage the rapid development and <br /> maintenance of large populations of common, non-pathogenic, <br /> �,.,. hydrocarbon-utilizing bacteria known to be efficient <br />
