United States Environmental Protection Agency Office of Solid Waste and Emergency Response (5102G) EPA-542-F-00-019 December 2000 www.epa.gov/tio cluin.org Innovations in Site Characterization Case Study: Site Cleanup of the Wenatchee Tree Fruit Test Plot Site Using a Dynamic Work Plan Fact Sheet and Order Form Introduction This case study (542-R-00-009) is one in a series designed to provide cost and performance information for innovative tools that support less costly and more representative site characterization. Case studies are prepared to offer operational experience and to disseminate information about how the efficiency of data collection can be improved. The ultimate goal is enhancing the cost- effectiveness and defensibility of decisions regarding the disposition of contaminated sites. Pesticide Site Cleanup Using a Dynamic Work Plan and Immunoassays Innovations in Site Characterization Case Study: Site Cleanup of the Wenatchee Tree Fruit Test Plot Site Using a Dynamic Work Plan (EPA -542-R-00-009) describes how systematic planning allowed the U.S. Corps of engineers to design and implement cleanup of pesticide- contaminated soils at this small site. Immunoassay kits for pesticides provided real-time results which guided a dynamic work plan to seamlessly integrate site characterization and cleanup (soil removal, segregation and disposal) with "surgical" precision. Expensive fixed laboratory analyses were reserved for demonstrating that decisions based on immunoassay data are reliable, and for generating a statistically valid data set to comply with State closure requirements. Characterization, cleanup and site closure activities were completed within a 4-month time frame. The entire project cost ($589K) was half the cost estimated under a more traditional site characterization and remediation scenario ($1.2 million) Key Features of the Project Leading to its Success: » Systematic planning achieved by a team representing the USAGE, EPA, the site owners, and state regulators with the appropriate mix of skills and decision-making authority. *• A conceptual site model based on a review of historical records from the site. * A dynamic work plan that permitted the field team to make real-time decisions on the basis of data generated in the field. > A pilot study that demonstrated the utility of the field analyses and provided comparability data which were used to establish site-specific action levels for use with the immunoassay kits. > An adaptive sampling and remediation strategy that relied on a combination of field analyses and fixed laboratory data. ------- United States Environmental Protection Agency National Service Center for Environmental Publications P.O.
