Soil Cleanup Objectives

In an ongoing effort that is being coordinated by the Illinois Fertilizer and Chemical Association, William Roy was asked to provide guidance and input to a Wisconsin-based consulting company for deriving soil cleanup objectives for three agrichemical dealerships in Illinois. There had been a release of anhydrous ammonia at each facility. To derive the cleanup objectives, Roy will use a new approach that was promulgated by the Illinois Department of Agriculture and is based on research conducted at the Illinois State Geological Survey. The new approach is gaining national acceptance. The new methodtakes into account the soil chemical properties of earth materials at the impacted site, where the method currently being used by the Illinois EPA does not. The results of this effort will be submitted to the Engineering and Assessment Unit of the Illinois Environmental Protection Agency.
