Wyckoff Generational Remedy Evaluation

The Wyckoff/Eagle Harbor Superfund Site is a former wood-treating facility located on Bainbridge Island, Washington. Within the Former Process Area on this site, it is estimated that over 1.2 million gallons of non-aqueous phase liquid (NAPL) is present in the subsurface. The U.S. Environmental Protection Agency is currently implementing a containment remedy for this portion of the site; however the Washington State Department of Ecology (Ecology) is interested in exploring alternative remedial actions for this area that will either remove the contamination or reduce its mobility. Floyd|Snider is assisting Ecology in a 9-month evaluation process that examines source removal or mobility reduction remedial alternatives for Wyckoff soil and groundwater that would be protective for multiple generations with little active management. This effort is being referred to as the Wyckoff Generational Remedy Evaluation. 

As part of this evaluation process, Floyd|Snider has helped in the formation of a panel of eight experts who  have experience in the remediation of sites with similar contamination and on large construction projects in challenging or constrained environments. The expert panel came together for a workshop on Bainbridge Island in January 2010 to identify, evaluate, and collectively brainstorm remedial alternatives for the Wyckoff Site. Floyd|Snider facilitated and managed this workshop. Additionally, Floyd|Snider is working with the Wyckoff Generational Remedy Steering Committee, made up of community and tribal representatives, throughout this process. Floyd|Snider facilitates the steering committee meetings and provides documentation services to the group in the form of meeting notes. The outcome of this evaluation process will be the identification of one to three remedial concepts that will form the basis for moving toward potential implementation, which Floyd|Snider will be summarizing in an Alternative Evaluation document.
