This website was first launched in 1996 and it is sponsored and operated by the U.S. Environmental Protection Agency. The Clean-Up Information (CLU-IN) website "provides information about innovative treatment and site characterization technologies to the hazardous waste remediation community." There are several sections worth a look here, and visitors might first want to check out the "Issues" tab near the top of the page. This section highlights emerging issues for site owners and others involved in the common areas where remediation is required. Visitors will find these areas, such as "Brownfields", "Wood Treater Sites" and "Remediation of Dry Cleaner Sites", on a drop down menu or listed on the right hand side of the Issues page. One section that should not be missed is the "Nanotechnology" section, which features an overview of how nanotechnology might be used in brownfield remediation. Back on the homepage visitors can out about upcoming web events, recent news, additional resources, and how to stay connected including podcasts, an RSS feed, and their TechDirect email service.
