The OFFICIAL LWG superfund site!

 

The Lower Willamette Group (LWG) is composed of the ten parties who signed agreements with EPA to conduct the remedial investigation and feasibility study of the Site and four other parties who have contributed financially to the project. The LWG is a small subset of potentially responsible parties identified by EPA. The members of the LWG are:

Portland Harbor Superfund Site

Portland Harbor Superfund Site | PDX water maps and messes | Scoop.it

Portland Harbor, Portland's industrial Port, was listed as a Superfund Site in 2000

The Portland Harbor Superfund site extends roughly from the Freemont Bridge to Sauvie Island and is located within the city of Portland (See map)

Marina Zurkow's insight:

Good resource links to reports from 2004-2010.

Willamette Cove

Willamette Cove | PDX water maps and messes | Scoop.it
Marina Zurkow's insight:

Willamette Cove is on river right, just downstream of the McCormick & Baxter Superfund site and the railroad bridge. Purchased as part of the Metro Greenspace program, the cove area consists of approximately 20 acres of beach and uplands. The upland area is contaminated with reatively low-grade petroleum-based products, and the beach has been treated as part of the adjacent McCormick & Baxter cleanup.

(GMW 7/8/97) This site was used as a lumber mill, plywood mill, barrel manufacturing, and a shipbuilding/repair and drydock facility (Port of Portland) until the 1960s. These past uses have resulted in local contamination in soil and groundwater at the site and possibly have affected sediment in the Willamette River.

Metals, PAHs and PCBs, are contaminants of concern in river sediment next to the Willamette Cove site and in shoreline sand and soil. These contaminants can cause adverse effects to site users and aquatic receptors.

PAHs, PCP (wood preservative), and certain metals from the adjacent McCormick & Baxter Superfund site (ECSI #74) have migrated in sediment and groundwater into the southeastern portion of the Willamette Cove site. A portion of the Willamette Cove shoreline is treated with a protective cap to prevent the continued release of M&B contaminants into the Willamette River. DEQ will not pursue Willamette Cove property owners for contamination attributable to M&B.

At low river stages in 2010 and 2011, a petroleum sheen is present emanating into the river from beach sand in the inner cove (east parcel).

In October 2010, trenches excavated to the water table beneath the east parcel beach exposed oily sand containing PCB Aroclor 1254 at a concentration of 207,000 ppb. Surface sand samples from the same beach did not contain elevated PCB concentrations. The specific manner and time of releases are not known, although on-site industrial activities between the 1930s and the 1960s are believed to be the likely sources of hazardous substances in upland soil. Waterfront activities at the former cooperage may have contributed to the petroleum and PCB contamination found at the Willamette Cove inner beach and contribute to the petroleum sheen on river water.

Contaminated sediment and groundwater from McCormick & Baxter (ECSI #74) have impacted the southeastern portion of Willamette Cove adjacent to the railroad bridge and abutment.

Heavy metals; PAHs; VOCs; PAHs; PCBs; dioxin and hydrocarbons have been found in uplands and shoreline soils, groundwater and beach sand.

Tributyltin (previously used as an anti-fouling paint to protect ship bottoms) has been detected in river sediments.

PCP and some PAH contamination in sediment and groundwater at Willamette Cove adjacent the railroad bridge abutment may be attributable to the adjacent McCormick & Baxter site (ECSI #74).
Pathways: Pathways of greatest concern for Willamette Cove are:

1) skin contact or swallowing of contaminated sediment or soil by aquatic organisms, birds, and mammals found in this stretch of the river.
2) consumption of resident fish and crayfish caught by fishermen.
3) ingestion of and skin contact with sediments and surface water during recreational use of beaches.
4) Human and ecological risk due to handling contaminated site soils.
(These use pattern may change as METRO intends to preserve the site as undeveloped greenspace)

use google maps (satellite view) to look at nearest address along shoreline, then punch in address to portlandmaps.com. go to "maps/businesses" and all the nearby leasees also show up.

A Guide To The Portland Harbor Superfund Site

A Guide To The Portland Harbor Superfund Site | PDX water maps and messes | Scoop.it

More than 100 years of industry on the Willamette River left toxic contaminants in the soil and river sediment downstream from downtown Portland. Extensive testing has found 29 different toxic compounds at levels that pose a risk to human health and 89 compounds that pose a risk to ecological health.
