## Summary

Investigations in and near the Site found many areas where surface and subsurface soils contained levels of arsenic and lead above what was considered background levels: 15 milligrams/kilograms ( mg/kg ) for arsenic and 400 mg/kg for lead. In particular, limited sampling of soils along the proposed route of the storm water drainage feature show arsenic levels up to 48 mg/kg and lead levels up to 1400 mg/kg and sampling on property adjacent to the proposed route showed arsenic levels up to 1400 mg/kg and lead levels up to 100,000 mg/kg. Levels of arsenic and lead well above background levels show a release of a hazardous substance to the environment at the Site. Excavation of these metal contaminated soils threaten additional releases of these hazardous substances to the environment.
