Cost Analyses for Remedial Options

Abstract

The economic analysis of remedial options is a key activity in any remedial selection process. It is typically employed in the feasibility study phase of remedy selection to aid in selecting the optimal remedial option for a site, in concert with a number of other criteria. In this case, for dissolved phase chlorinated solvent contaminated groundwater, the capital and recurring costs of various alternatives are compared, typically using a net present value (NPV) calculation. In addition to the ability to compare remedial options, detailed economic analysis also allows the design engineer to determine which cost elements of a specific remedy drive the cost of that remedy. Understanding the primary cost drivers improves the potential for cost optimization and therefore can lead to more cost effective remedial designs.
