How clean is clean – must a Brownfield site be cleaned up to pristine conditions?
The extent of cleanup will vary considerably depending on the type, amount and area of contamination, and the cleanup standards used by the specific regulatory program that governs the cleanup. In addition, a key factor in determining the level of cleanup is whether the use of the property is taken into account in setting cleanup standards. For example, if a property is slated for industrial use, the cleanup standards may be less stringent than if the property were to be used for residential purposes, because the level of exposure to the contaminants will be less.
