The impacted soils were excavated based on visual evidence of contamination and containerized for
proper disposal. Two samples were collected for analysis of volatile organic compounds and
polychlorinated biphenyls (PCBs): one from the impacted soils and one from the subsurface after cleanup
to verify that residual soil contamination concentrations are below applicable soil standards. Laboratory
analysis for volatile organic compounds, total metals, and polycyclic aromatic hydrocarbons found
concentrations were below the residential Soil Remediation Levels (Arizona Administrative Code R18-7-
200, Appendix A) for all contaminants. The laboratory report is attached.
