\ BooknewsThis is one of eight proceedings volumes from the April 1999 symposium. Thirty-four papers focus on treating vapor, water, slurries, and soils to meet challenges in bioremediating sites and wastestreams by using bioreactors and other technologies away from the original site, sometimes singly and sometimes in combination with other technologies. They discuss such technologies as slurry, compost, packed-bed, and vapor phase reactors; biopiles; and biofilters to remediate media contaminated by arsenic, TPHs, MTBE, heavy metals, solvents, and other waste.
