- NATURAL ATTENUATION STUDY IN WISCONSIN AND ILLINOIS. A natural attenuation field study conducted jointly by the EPA Region 5, Wisconsin Department of Natural Resources (WDNR), the Illinois Environmental Protection Agency (IEPA), and Amoco Corporation (Amoco). This project, initiated in October 1994 has goals of determining the effectiveness of natural attenuation and developing a cost-effective way to evaluate it. For more information about this report, contact Yves Reme of EPA Region 5.
