Planning for Soil Contamination A good tool for avoiding this surprise upon excavation is: The Michigan Environmental Mapper.
Sites the Mapper Will Show: • UST Releases (Active) • UST Releases (Closed) • Part 201 Contamination Sites • Site Names and contaminant • Questions can be addressed to the DEQ Remediation Division
The Big Question? • What if I need to put utilities through contaminated soil or groundwater?
Working in Contaminated Soil • Meet HAZWOPPER standards. • Soil may generally be put back. • Isolation for water mains. • Water pumped from excavation must not cause or exacerbate contamination.
