| Short description: |
Note: this report discusses sustainability in terms of the persistence of the MNA effect, not in terms of sustainable development
The
framework consists of methods for assessing the balance between
the delivery of contaminants to the environment and their
natural attenuation.
|
| Long description: |
This study illustrates that the short- and long-term sustainability of MNA can be assessed by:
Estimating the time required for contaminants to dissolve/disperse/degrade under ambient hydrologic conditions (time of remediation).
Quantifying the organic carbon flux to the system needed to consume competing electron acceptors (oxygen) and direct electron flow toward chloroethene degradation (short-term sustainability).
Comparing the required flux of organic carbon to the pool of renewable and non-renewable organic carbon given the estimated time of remediation (long-term sustainability).
These are general principles that can be used to assess the sustainability of MNA in any hydrologic system.
