Marina And Yacht Facility

Farallon conducted a detailed site characterization and cleanup action at a marina fueling and yacht maintenance facility in Anacortes, Washington. Site characterization included a direct-push drilling investigation to delineate the extent of impacts of a release of diesel fuel from a UST located adjacent to Fidalgo Bay.

Based on the results of the site characterization, Farallon delineated multiple commingled contaminant plumes and performed a cost-benefit analysis of remedial alternatives leading to selection of a cost-effective cleanup action protective of human health and the environment. The cleanup action included decommissioning and removal of two 12,000-gallon-capacity USTs; excavation, segregation, and disposal of approximately 1,200 cubic yards of petroleum hydrocarbon-impacted soil; groundwater management during the excavation activities; and application of an oxygen-releasing compound to provide oxygen-enhanced subsurface conditions, accelerating the natural degradation of residual petroleum hydrocarbons. Farallon facilitated site restoration activities that included engineering design and construction of a soil cement subgrade and reinforced concrete slab capable of supporting a 45,000-pound marine travel lift. Farallon installed a groundwater monitoring network and conducted quarterly sampling for 1 year that demonstrated the success of the cleanup action in achieving MTCA cleanup levels for groundwater. The technical support services provided by Farallon resulted in an efficient and cost-effective cleanup solution in a sensitive marine area that also met the site owner's goal to allow continuing operations of a functional marina and maintenance facility during the cleanup action.
