FOREWORD
EPA is charged by Congress to protect the Nation's land, air and water systems. Under a mandate
of national environmental laws focused on air and water quality, solid waste management and the control
of toxic substances, pesticides, noise and radiation, the Agency strives to formulate and implement actions
which lead to a compatible balance between human activities and the ability of natural systems to support
and nurture life.
The RobertS. Kerr Environmental Research Laboratory is the Agency's center of expertise for
investigation of the soil and subsurface environment. Personnel at the laboratory are responsible for
management of research programs to: (a) determine the fate, transport and transformation rates of pollutants
in the soil, the unsaturated and the saturated zones of the subsurface environment; (b) define the processes
to be used in characterizing the soil and subsurface environment as a receptor of pollutants; (c) develop
techniques for predicting the effect of pollutants on ground water, soil, and indigenous organisms; and
(d) define and demonstrate the applicability and limitations of using natural processes, indigenous to the
soil and subsurface environment, for the protection of this resource.
In-situ bioremediation of subsurface environments involves the use of microorganisms to convert
contaminants to less harmful products and sometimes offers significant potential advantages over other
remediation technologies. This report provides the most recent scientific understanding of the processes
involved with soil and ground-water bioremediation and discusses the applications and limitations of the
various in-situ bioremediation technologies.
