Description: Ecology’s Toxics Cleanup Program (TCP) works to clean up contaminated properties throughout Washington state. Cleanup projects vary greatly in size and complexity. Some are small and routine, like cleaning up contamination from a leaking underground storage tank. Many cleanups are large, complex projects that require engineered solutions. In addition, TCP regulates more than 8,900 underground storage tanks at more than 3,400 facilities (both private businesses and public entities). We work to ensure that these tanks are installed, managed, and monitored in a manner that prevents releases into the environment.

Description: This map shows the general pattern of arsenic contamination from Ruston (Tacoma Smelter Plume) By Census Block Group. With 90% certainty, at least 1 in 10 parcels will have soil arsenic at or above levels shown. Predictions are based on distance and direction from the former Asarco smelter, and on sampling data from forested and other soils undisturbed by development. Actual arsenic levels may vary greatly from parcel to parcel.

Description: Historical aerial photos were used, based on availability and coverage, from dates between 1945 and 1955 to generate shapefiles depicting the footprint of historical orchard properties. As a resource images from USGS Earth Resources Observation and Science (EROS) Center were downloaded and georeferenced. Polygons were digitized outlining apparent orchard property, based on the best interpretation of staff performing the work. A single shapefile for the following counties were produced: Klickitat, Benton, Yakima, Chelan, Douglas and Okanogan.
