Description: The Washington State Parcels Project provides a statewide data set of tax parcels and ownership/taxpayer attributes that cover those counties that currently have digital tax parcels. Attribute data has been normalized so that the field names are the same across all counties. The data set contains the tax parcel identification number, the owner/taxpayer name and address information, and the Department of Revenue land use codes.

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.
