EPA understands that site owners and other parties involved in remedial activities need information on emerging issues. CLU-IN Issue Areas bundle available information associated with these topics. These issue areas not only draw upon existing resources from the CLU-IN Web site, but also from other sources of information that were not previously cited or available on CLU-IN. These topics are still being researched, and these issue areas will be updated with information from federal cleanup programs, state sources, universities, nonprofit organizations, peer-reviewed publications, and public-private partnerships. We welcome any suggestions you may have for new topics or additional resources.
