Abstract: Bioremediation is a process in which organic contaminants present in soil, sediment or groundwater are degraded into innocuous compounds such as carbon dioxide and water by microbes. The contaminants are degraded naturally by the microbes using processes that occur as a part of their metabolism. The microbes utilize the contaminants as a source of carbon and energy. Bioremediation is a passive technology and is a component of natural attenuation. It is a publicly acceptable alternative to more traditional technologies. Site conditions can be manipulated to enhance in situ bioremediation processes and speed up degradation rates of contaminants. Biological activity can be stimulated by the injection of suitable electron acceptors and carbon/energy sources, nutrients and microbial cultures. The specific contaminants and the site conditions determine which parameters will be manipulated. Overall, bioremediation is often more economical than traditional remedial technologies. CRA has conducted many bench-scale and pilot-scale studies and implemented full-scale treatments for the bioremediation of chlorinated solvents and fuel related hydrocarbons in soil and groundwater.
The details provided in this section/seminar will provide for the basics of enhanced bioremediation for CRA personnel functioning in the role project manager and/or project engineer.
This seminar will provide the participants with an overview of methods of assessing the potential for successful application of enhanced bioremediation.
- Contaminants treatable by bioremediation;
- Site Assessment tools to determine if aerobic or anaerobic conditions exist;
- Application and use of electron acceptors and carbon/energy sources, nutrients and microbial cultures;
- Treatability and Field Pilot Studies; and
- Examples of bioremediation projects performed by CRA.
