Abstract

Some environmental contamination simply cannot be cleaned up. US Environmental Protection Agency (USEPA) has rules for determining when this is the case (i.e., when technical impracticability precludes cleanup). In such cases, an alternative response must still be health protective and containing. One condition that often leads to a conclusion of technical impracticability is when dense nonaqueous phase liquids (DNAPLs, e.g., tarry, oily, or otherwise immiscible liquid chemicals) are present in the subsurface. When DNAPL is known to exist, it might be more efficient to declare technical impracticability and move to “plan B” rather than wasting time and money on a “plan A” cleanup destined for failure.
