Project Life Cycle Stages
Geospatial methods can apply throughout the life cycle of environmental cleanup projects, including monitoring of active remediation systems. The terminology and regulatory framework for the stages of the project within its life cycle, however, often vary under different regulatory programs. For clarity, this guidance organizes site management around five main tasks: release detection, site characterization, remediation, monitoring, and closure. These life cycle stages are appropriate for most groundwater remediation projects and apply to other media as well.
These tasks correlate with the activities described in various regulatory programs (such as RCRA, CERCLA, State Voluntary Cleanup, and UST Site Cleanup). Although individual projects may vary in their progression through these stages, statistical tests can support decision making regardless of how the project stages are defined. Figure 126 summarizes the correlations between the terms used in this guidance document and the terms used in several regulatory programs.
