The Triad approach compresses the cleanup process by consolidating several steps of the process into fewer field activities.
The Triad approach is particularly effective at compressing the cleanup process where regulations and the site-specific situation allow, consolidating several steps of the cleanup process into fewer field activities. Situations that are conducive to schedule compression include those where (1) regulatory-mandated public comment and sequential milestones are not required, (2) a preferred remedial alternative has been established, (3) contaminants of concern have been identified, (4) well-defined cleanup objectives for the contaminants of concern are available, and (5) budgetary flexibility exists to accommodate uncertainty in final project costs. In these cases, characterization, remediation, and closure activities can be combined in one set of field activities.
