Hide details for Site DescriptionSite Description

A chrome plating facility operated on the 12-acre site located in Portland, Oregon, from 1957 until the late 1980s. The operation generated electroplating wastes and waste water containing heavy metals and cyanide. For more than 25 years, the company discharged plating waste water without treating it. Before 1969, the water was discharged onto a low-lying area of the property, which drained into the Columbia Slough. After 1969, land filling cut off the site drainage, and the plating waste created a surface impoundment. In mid-1985, during an EPA inspection, the banks of the pond were found to be eroding, and the natural drainage channels were filled with refuse. Shortly thereafter, the owner pumped the contents of the pond into the Portland sewer system. In 1978, the company detected metals in an on-site well and in industrial and municipal wells located within two miles of the site. Approximately 20,000 people live within three miles of the site. Public and private wells within three miles of the site provide drinking water for about 1,500 people. The Columbia Slough, which drains into the Willamette River, lies about 600 feet northeast of the site.

Site Responsibility: This site has been addressed through Federal actions.

Media Affected: Groundwater, Soil & Sludges, Surface Water
Groundwater, surface water, and soil were contaminated with heavy metals, including chromium, nickel, copper, and lead. Soil also contained cyanide. Chromium, copper, nickel, and lead were present in sludge on the site. Contaminated groundwater, soil, and sludge posed a potential hazard through direct contact or accidental ingestion. Drainage from the site potentially contaminated the Columbia Slough.

Hide details for Cleanup ProgressCleanup Progress

Early Actions: In 1992, EPA conducted an early cleanup action. At this time, 1100 cubic yards of contaminated soil and sludge were excavated from the site and treated and disposed of in an off-site landfill.

Long-Term Actions: In 1993, EPA determined that no further actions were required at the site. However, to ensure that groundwater is not used in the future, EPA required the property owner to place a restriction on the deed for the property preventing future groundwater use.

The site was deleted from the National Priorities List (NPL) on November 11, 1994.
