CORNWALL AVENUE LANDFILL
Aerial view of the Conrwall Ave Landfill cleanup site
The Cornwall Avenue Landfill cleanup site is located on the Bellingham waterfront between Boulevard Park and the former Georgia Pacific pulp mill, and is most recognizable today for the large mounds covered with white plastic. It's at the south end of Cornwall Avenue. About 13 acres of the site are on land, and about 3.5 acres are in water.
- 1888-1946: The site was used for sawmill operations, including log storage and wood disposal.
- 1953-1965: The site was used as a municipal waste landfill.
- 1965: Upon closure of the landfill, the site was covered with a layer of soil.
- 1971 to 2005: The site was used for log storage and warehousing operations.
- 2011: Interim action
The site investigation found an estimated 295,000 cubic yards of municipal waste and 94,000 cubic yards of wood waste. Some of the contamination associated with this waste includes:
The investigation found tannins and lignins associated with wood waste breakdown products; elevated nitrogen compounds like ammonia; elevated dissolved metals like manganese; and volatile organics like benzene in the ground water.
The investigation found phthalates, PCBs (polychlorinated biphenyls), PAHs (polycyclic aromatic hydrocarbons), phenols, and diesel and oil-range petroleum hydrocarbons in the sediment.
Contamination from neighboring sites
Contamination from two neighboring cleanup sites overlaps with contamination at the Cornwall site. Petroleum hydrocarbons, pentachlorophenol, carcinogenic PAHs, and other contaminants associated with former wood treating operations at the adjacent R.G. Haley site are present in the soil, sediment and groundwater. And mercury associated with the Whatcom Waterway site is present in the sediment.
2013 - Published final environmental report.
2014 - Public review of consent decree, cleanup action plan, and engineering design report.
2014 – Design and permitting for project.
2015 – Begin cleaning up site.
COORINDATED BELLINGHAM BAY CLEANUP WORK
The Cornwall Avenue Landfill cleanup site is one of 12 cleanup sites in the Bellingham Bay Demonstration Pilot project, a coordinated bay-wide effort by federal, tribal, state and local governments to clean up contamination, control pollution sources and restore habitat, with consideration for land and water uses. The work is informed by the Bellingham Bay Comprehensive Strategy, completed by the pilot work group in 2000.
