Pump-and-Treat (P and T) technology has been widely applied for groundwater remediation across many types of sites and for multiple types of contaminants. Decisions regarding major changes in the remediation approach are an important element of environmental remediation management for a site using P and T. An evaluation approach that includes an assessment of P and T system performance is under development to facilitate remediation decisions for P and T systems. The approach provides information on technical data and analyses that can be used to support remediation decisions. The document is organized to help decision makers distinguish between several categories of decision outcomes. These outcomes include 1) Initiate Remedy Closure, 2) Transition P and T to Monitored Natural Attenuation, 3) Continue P and T, 4) Supplement P and T with Another Treatment Technology, 5) Transition from P and T to Another Treatment Remedy, and 6) Transition P and T to an Alternative Closure or Contamination Management Approach. Key triggers that support selection of the appropriate outcome are provided, along with a description of suitable supporting data needed to formulate the technical basis for a remediation decision.
