Dynamic Field Activity Case Study: Soil and Groundwater Characterization,
Marine Corps Air Station Tustin A dynamic field activity was used to characterize contamination at Marine Corps Air Station Tustin in 1995 and 1996. This case study describes and evaluates the results from one of the sites on this military base. The case study shows that the dynamic field activity saved at least 15 percent of the project cost and over 60 percent of the project time.

| Dynamic Field Activity Case Study: Soil and Sediment Cleanup, Loring Air
Force Base A dynamic field activity was used to cleanup PCB, lead, pesticide, and PAH soil/sediment contamination at Loring Air Force Base in 1997 and 1998. This case study shows that the on-site decision making process used to remove and dispose contamination saved the Air Force 50 percent of the analytical costs, 25 percent of the total project costs, and 33 percent of the time this project would have otherwise required.

| Dynamic Field Activity Case Study: Treatment System Optimization,
Umatilla Chemical Depot A dynamic field activity was used to optimize the treatment of RDX and TNT contaminated groundwater at the Umatilla Chemical Depot in northeastern Oregon in 1999. This case study shows that the on-site decision making process used to manage the treatment system is providing the Army an annual savings of at least 45 percent. (444K/40pp/PDF) |

Dynamic Workplans and Field Analytics: The Keys to Cost-Effective
Site Cleanup This case study provides cost and performance information for a soil and groundwater characterization at Hanscom Air Force Base. Contaminants included VOCs, PCBs, PAHs, and metals. The cost savings were calculated to be between 36 and 57 percent.

TCE Plume Characterized Using Field Portable GC/MS  This technology evaluation report describes deployment of the HAPSITE GC/MS by an analytical service provider to produce low-cost, real-time VOC data in the field using EPA Method 8260. The U.S. Army Corps of Engineers (USACE) used the data to make real-time decisions concerning borings placement and long-term monitoring wells installation within a single field mobilization of 3 weeks. The USACE estimated they saved $27,000 (26% of total projected costs) and 4 days of field time over project costs that would have been incurred if fixed laboratory analyses had been used. The report includes a summary of the QA/QC protocol used and project-specific analytical performance. (750K/34pp/PDF) |
| Innovations in Site Characterization Case Study: Site Cleanup
of the Wenatchee Tree Fruit Test Plot Site Using a Dynamic Work
Plan The Wenatchee Tree Fruit Research and Extension Center site contained soils contaminated with organochlorine pesticides, organophosphorus pesticides, and other pesticides due to agriculture-related research activities conducted from 1966 until the mid-1980s. The U. S. Army Corps of Engineers used a dynamic work plan guided by field analyses to seamlessly integrate the site characterization and cleanup portions of the project. (501K/46pp/PDF) |
| Dexsil L2000 PCB/Chloride Analyzer for Drum Surfaces This case study demonstrates how a PCB field method was used for on-site decision making in the treatment of PCB contaminated drums. The PCB analyzer was able to provide DOE officials with the rapid data they needed in determining that the treatment technology was not working, allowing them to abort the project before additional resources were expended.
