The screening analysis presented in this report can be used to quickly determine if significant cost savings may be achieved by altering key aspects of an existing or planned pump-and-treat system. The spreadsheet-based screening analysis allows quick and inexpensive cost comparison of competing alternatives at a site, in terms of Net Present Value (NPV). Site-specific values input to the spreadsheet can be based on very detailed engineering calculations and modeling results, or may be based on 'ballpark estimates'. The suggested approach includes a 'checklist' of important site-specific factors to evaluate, and requires the formulation of potential system modifications. System modifications may be postulated with respect to the same goals as the present system, or with respect to modified goals.
