8.1 Introduction
During the course of project CU-720, researchers and engineers in Federal
Integrated Biotreatment Research Consortium (FIBRC) conducted basic
research and developed treatment processes, many of which were scaled
up to pilot- or field-scale implementation. In the course of this work, a
number of research and developmental issues were identified as worthy of
following up but were not pursued due to a desire to move the technology
with the most potential to the pilot or field scale. The following issues were
identified in each of the thrust areas as frontiers of science and technology
in bioremediation.
8.2 Polycyclic aromatic hydrocarbons
In theory, soils contaminated with polycyclic aromatic hydrocarbons (PAHs)
may be treated utilizing various cleanup strategies. However, many pro-
posed strategies have significant economic and feasibility problems. What
is needed is an effective technology that supports the economics of disposal,
eliminates adverse contaminant impacts, and supports the reuse of treated
contaminated soils. Regardless of whether the biotreatment system is passive
