Brownfield Remediation Projects

Brownfields Cleanup Project/Characterization and Remediation – Former Willamette Industries Facility, Sweet Home, OR (August 2014)

Full scale investigation and cleanup from heavily contaminated mill site facility located along the Santiam River. Our investigation involved several phases of work including soil & groundwater quality evaluation and contaminated soil remediation. Creekside also completed a comprehensive risk assessment and prepared a Contaminated Media Management Plan for our confidential client.


Brownfields Cleanup Project/Characterization and Remediation – Former Eyerly Aircraft Repair Facility, Salem, OR (January 2005 to December 2012)

Full scale cleanup from heavily contaminated aircraft maintenance and repair facility to military installation post for Oregon Dept. of Military; main chemicals of concern: Chromium, lead, petroleum hydrocarbons, VOCs. The environmental team of Creekside Environmental Consulting, L.L.C., General Client Services, Inc., and Scientec Inc. with chemical engineering provided by Univar and FMC Corporation and Bio-remediation consultation provided by Robert Radcliffe of Bioremediation Corporation, in a collaborative effort has recently completed the characterization of soil and shallow groundwater contamination beneath a 4.5-acre site (Jack Eyerly Trust Property) located on Turner Road SE, in Salem, Oregon. Based on that work, the environmental team developed, and has completed, remediation actions for contaminated site soil and shallow groundwater. Detailed information on all characterization and remediation activities has been provided to the Oregon Department of Environmental Quality (ODEQ) on an ongoing basis via weekly reports, project meetings, technical memorandums, emails, phone conversations, and numerous figures and tables. No Further Action determination has been recommended by DEQ.


Portland Harbor Source Control Evaluation – Peninsula Iron Works, Portland, Oregon (July 2012 – Present)

Based on City of Portland’s recently completed industrial source control study, Peninsula Iron Works was identified as a potential source of contamination to the Portland Harbor at Basin 52 near Cathedral Park on the east side of the Willamette River. A Strategy Recommendation was completed & DEQ determined a Preliminary Assessment (PA) on the subject property should be conducted. Creekside completed the PA in July 2005, and prepared a work plan for DEQ which involved hot spot removal of PCB-impacted soils. Creekside provided construction oversight during remediation, collected confirmatory samples, prepared an ecological risk assessment, and successfully obtained an NFA from DEQ in May 2006.

Completed extensive Phase II Environmental Site Assessment including records review, hydrogeologic, surface water, soils and ecological risk evaluations; agency file search; personnel interviews; research of environmental investigations on the subject site and on neighboring properties; and pond and sediment sampling and analysis at a former log pond facility owned by Hampton Lumber Company. Met with City of Willamina and the Oregon Department of Environmental Quality to discuss the investigation results and prepared a work plan to remediate onsite contamination. Target constituents include petroleum hydrocarbons, regulated metals, Sapstain, and volatile organic compounds. Project is in progress and cleanup has not yet been authorized.


Residential Cleanup Project/Characterization and Remediation – Former Ken Foster Farms Site, Sherwood, OR (November 2005 – April 2009)

In November 2005, Creekside was hired to complete a Phase 2 ESA for 5 acres of residential land that was previously referenced as the Former Ken Foster Farm Site. It was reportedly impacted with chromium-contaminated waste deposits originating from the Former Frontier Leather Tannery facility located about ¼ mile to the north. During our Phase 2 investigation, we confirmed that the property was impacted with Frontier Leather wastes. Shortly thereafter, Creekside was hired to conduct a full scale environmental investigation and cleanup of 4 acres which had been selected for residential redevelopment. During the 3 years we were involved, the Creekside Team collected hundreds of onsite samples (shallow soil, groundwater, pond water, pond sediments, and waste piles) and arranged for analysis of total and hexavalent chromium which were the primary chemicals of interest. We completed an Interim Remedial Action Measure (IRAM) plan and also managed the removal and on-site placement (into an Engineered Soil Cell) of over 8,000 tons of chromium-impacted soil and debris. Creekside also completed human health and ecological risk assessments and submitted final reports to DEQ. Our services for this project included preparing work plans, permits, and reports for our client with oversight and approval from DEQ. By April 10, 2009, our client obtained “No Further Action (NFA) determinations for all four 1-acre lots from DEQ which allowed him to market the property for redevelopment or for sale.
