Phase II/Soil Borings

When soil contamination is suspected, a subsurface investigation is the first step in evaluating whether the property requires cleanup.

A Phase II Investigation generally consists of soil borings, laboratory analysis and data assessment. After the level and extent of contamination are established, the owner, buyer or lender (or occasionally the Illinois Environmental Protection Agency) decides if formal closure is necessary or desirable for the property.
