Site Characteristics

General Site Description:
Site History:
Contamination Information: (4/12/02 CWH/SAP) In 1988, the Port of Portland began evaluating the extent of pollution in this area, and commissioned an RI/FS report in 1996. Some remedial actions were performed from 1996 through 1997. 11/3/16 Perfluorinated compounds have been identified as a potential contaminant of concern, associated with AFFF (aqueous film forming foam) used for fire suppression training at this location, as well as historical and current fire station facilities on the PDX property. In 2020, the Port indicated to DEQ that City of Portland previously operated the Alderwood Road Fire Station, located at 7210 NE Alderwood Road. The station is currently in use by the Port for non-fire fighting activities.
Manner and Time of Release: Overview: historic release of contaminants associated with a variety of site activities including petroeum storage and use (gas, diesel, jet fuel), aviation cleaning and maintenance, storage and use of fire-fighting foam (AFFF).

Fire training specific: From 1963 through 1989 fire-fighting training was conducted in the two pits. Depression areas or mock-ups were filled or dosed with jet fuel, diesel or other flammable liquids and then ignited. Both areas were bare ground. Seepage of liquids into soil occurred during this time period. An estimated 24,000 gallons of fuel were dosed and ignited at the Former FFTP annually during its operation.

11/3/2016 Current fire training activity is performed in the vicinity of the historical fire training pits, both of which have been capped by the Port of Portland independent of DEQ. Current fire training occurs in a lined containment basin, eliminating the potential for environmental releases.
Hazardous Substances/Waste Types: Petroleum hydrocarbons, oil, grease, acetone, BTEX, PAHs, chlorinated solvents (TCE and degradation products), PFAS associated with historical fire training.
Pathways: Direct contact with soils. Fugitive dust or vapor. Potential pathway to surface waters via storm drainpipe that underlies Former FFTP. Also, potential for groundwater-to-surface water migration.
Environmental/Health Threats: Particulate and soil exposure to maintenance workers. Skin contact and vapor inhalation exposure to utility workers (subsurface).
Status of Investigative or Remedial Action: (7/9/02 CWH/SAP) Added to ECSI; site screening performed. Based on this initial evaluation, Site Assessment has determined that a more detailed site investigation is required. This is a medium priority for state follow-up.

In September 2016 DEQ requested that the Port investigate potential releases of perfluorinated compounds associated with fire-training activities at the site.
