Advantages and Limitations of Bioremediation
The use of intrinsic or engineered bioremediation processes offers several potential advantages that are attractive to site owners, regulatory agencies, and the public. These include:
1. Lower cost than conventional technologies.
2. Contaminants usually converted to innocuous products.
3. Contaminants are destroyed, not simply transferred to different environmental media.
4. Nonintrusive, potentially allowing for continued site use.
5. Relative ease of implementation.
However, there are some limitations to bioremediation as well, these include:
1. Difficult to control the laboratory optimized conditions in the field.
2. Amendments introduced into the environment to enhance bioremediation may cause other contamination problems.
3. May not reduce concentration of contaminants to the required levels.
4. Requires more time.
5. May require more extensive monitoring.
