Description Groundwater samples for dissolved metals and WAD cyanide were collected in May and September 2011 from the former American Plating site in Tacoma to provide post-interim action groundwater data.

Dissolved chromium, copper, and nickel continue to be detected at low concentrations in the groundwater at the site. With the exception of the occasional anomalous result and WAD cyanide, most concentrations are below the regulatory site cleanup levels. However, further reduction in measured concentrations may occur due to natural attenuation processes as groundwater flows toward the regulatory point of compliance along the banks of the waterway.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
