Evaluation and selection of remediation techniques for a particular
situation requires the definition of assessment criteria. Weightings
should be applied to assessment criteria for use in a multi-criteria
analysis to determine the most appropriate technique.
Examples of assessment criteria include:
Seepage reduction required
Durability of remediation material
Installation costs
Cost-benefit analysis
Affordability
Environmental impact of technique during and
after construction
Operation and maintenance requirements
Occupational health
and safety requirements
Ease of construction
The criteria can also be used to focus the selection of potential
techniques. For example, if a seepage reduction of 95% is a
key criteria, then techniques with lower seepage reduction
rates need not be investigated.
