Farallon’s site characterization efforts resulted in identification of a second likely source of contamination at the Site, leading to the development of an independent remedial action plan to address soil and groundwater contamination. Farallon oversaw the excavation and disposal of approximately 4,000 tons of petroleum-contaminated soil. To remediate contamination left in-place at the site due to proximal active railroad lines and subsurface utilities that included a sensitive fiber-optic cable, Farallon designed and directed the installation of an LNAPL cut-off and recovery wall. Ongoing groundwater monitoring has demonstrated the effectiveness of the combined source-removal efforts and installation of the cutoff wall in mitigating migration of petroleum hydrocarbons in groundwater at the facility.
Active Railyard
Farallon completed a detailed site characterization effort to develop and implement strategies at an operating railyard facility in Bellingham, Washington. As a result of past petroleum hydrocarbon releases, soil and groundwater contamination that included a light nonaqueous-phase liquid (LNAPL) plume had been identified at the site, and groundwater remediation activities had been initiated. The property owner requested that Farallon evaluate the site history and available environmental investigation information, conduct an assessment of current site conditions and groundwater characteristics, and provide an evaluation of technically feasible alternatives to expedite the cleanup of soil and groundwater.
