Site Characteristics

General Site Description: The former refuse incinerator site is on an approximate 9-acre tract of land currently occupied by Chimney Park (Portland Parks & Recreation) and a City of Portland Records Storage Archives building. North Columbia Boulevard borders the site along the northeast; North Terminal Road borders the site on the south. The former Union Carbide Corporation site (ECSI #176, now owned by Oregon Steel Mills) borders the site to the north and west; a Union Pacific Railroad spur (to Port of Portland Terminal 4), and Pier Park (Portland Parks & Recreation) lie to the south of Terminal Road. Auto wrecking yards and the former access road to St. Johns Landfill lie beyond Columbia Boulevard, to the east. Columbia Slough is 0.25 mile the east of the site.
Site History:
Contamination Information: Toxic metals (As, Cd, Pb, Zn) and carcinogenic PAHs were detected in a 10-foot soil boring in 1989 (USEPA). Pb and Zn concentrations were somewhat higher than anticipated background levels. The Cd concentration was at least 8 times the anticipated background level. As concentration was 7 to 10 times anticipated background level, 14 times Industrial Soil Cleanup concentration, and greater than residential Hot Spot level. Carcinogenic PAHs Residential Soil Cleanup concentrations. The benzo(a)pyrene concentration exceeded the acceptable risk level for industrial properties. Two soil borings were advanced 9/25/00, each 30 feet from the 1989 EPA boring; they encountered relatively low concentrations of PAHs at about 1 foot bgs, but no detectable PAHs at 10, 12, or 20 feet bgs. One shallow subsurface sample contained chrysene at a concentration (0.106 ppm) just slightly above DEQ's Residential Soil Cleanup Level of 0.1 ppm. No metals were detected at concentrations above those expected to occur naturally in the site vicinity.
Manner and Time of Release: Unknown. Contaminant characteristics suggest incinerator ash. Unclear if incinerator ash was buried at the site.
Hazardous Substances/Waste Types: Toxic metals (especially arsenic) and carcinogenic PAHs, presumed to have originated from refuse burner ash.
Pathways: It is unknown if contamination is present on the ground surface or in groundwater. Surface contamination could represent a threat to on-site workers or members of the public that use Chimney Park for recreation. Potential surface runoff could represent a threat to Columbia Slough. Subsurface soil contamination could represent a threat to utility trench workers (incidental ingestion, direct contact, or dust inhalation), although the site's subsurface contamination does not appear to approach subsurface stormwater sewer lines at the site. Any groundwater contamination present could threaten aquatic life in the Columbia Slough, or consumers of fish caught from the slough.
Environmental/Health Threats: Potential health threats to utility trench workers, on-site workers, public park users, aquatic life within Columbia Slough, or consumers of fish caught from the slough.
Status of Investigative or Remedial Action: This site first came to Site Assessment's attention because of soil analyses conducted by EPA during a 1989 Site Inspection of the neighboring Union Carbide Corporation site (ECSI #176). A discrete composite soil sample collected from a 10-foot-deep boring on the City's property had elevated concentrations of carcinogenic PAHs and several toxic metals. The sample was originally collected as a "background" soil sample for the Union Carbide site. The elevated metals and PAH concentrations, and lack of low-molecular-weight PAHs suggest that incinerator wastes may have been buried at the site. It is unclear, however, if the sample represents a "worst-case" example of site soils contamination, or if shallower soil contamination or groundwater contamination is also present. (2/16/01 SMF/SAS) Additional subsurface soil samples collected in September 2000 indicate that deeper subsurface contamination is probably not widespread, although PAHs are present in shallow subsurface soils. Chrysene was detected in one shallow soil sample at a concentration slightly higher than DEQ's Residential Soil Cleanup Level. Re-examination of site priority indicates that a medium priority should be assigned for conducting an expanded preliminary assessment (XPA). (2/22/02 MTP/VCP) Based on a recently revised policy regarding potential sources to the Columbia Slough, the site is now considered a high priority for completion of an XPA to: 1) assess potential pathways from the site to the Columbia Slough via storm drain line #54; and 2) determine the volume, location, and composition of waste ash that may be present at the site.
Data Sources: Soil analyses are from a single discrete composite sample that EPA collected as a background soil sample during a 1989 Site Inspection of the neighboring Union Carbide Corporation site (ECSI #176): Site Inspection Report for Union Carbide, Portland, Oregon, TDD F10-8901-022, PAN FOR0231SA, by Ecology and Environment, Inc., December 1989.
