Brownfield Site Cleanup & Remediation

 Photos showing before and after cleanup
at an industrial site in Oregon

Creekside has completed over 25 assessment and cleanup projects which are generally recommended for those sites where recognized environmental conditions (RECs) have been identified. Creekside’s cleanup projects typically include sampling of onsite soil, groundwater, building materials (for asbestos) and drummed wastes, and the preparation of a summary report.

Additionally, Creekside will pursue obtaining a No Further Action (NFA) status with the Oregon Department of Environmental Quality (DEQ) for the site.  Approximately 20 of Creekside’s projects have resulted in the site obtaining an NFA from DEQ. A listing of all the NFAs Creekside has helped obtain can be provided upon request.

Creekside completed a full-scale demolition and cleanup of a former battery site in southeast Portland, we decommissioned 16 USTs for Eastman Chemical Company in NW Portland, we managed the OKI Semiconductor facility closure and site cleanup located in Tualatin, Oregon; and we managed the cleanup of a former tannery (federal and State superfund site) in Sherwood, Oregon. These projects included collecting, documenting and reporting the results for hundreds of samples collected from facility surfaces, soil, groundwater, storm water, and solid waste management units.
