The Site is the location of a former unpermitted auto scrapping business that ceased operation on or about 2005 (Figure 1). The Site use is presently residential. There is substantial information indicating that human health impacts are present at the Site because of the presence of elevated concentrations of lead (Pb) in surface and subsurface soils at the Site. On 19 November 2015 USEPA, Region 10 began a Removal Site Assessment (RSA) at the Site. The RSA confirmed extremely elevated concentrations of Pb throughout the Site.
