Environmental Technology Verification (ETV) programs currently exist in the U.S. and Canada, and a European ETV scheme is now being established. A European Commission-funded cooperative project has been launched to develop approaches to facilitate recognition and acceptance of ETV data among ETV programs. The project, called AdvanceETV, is currently seeking vendors that would like to have their technologies verified concurrently in the U.S., Europe, and Canada. The objective is to test candidate technologies once and the results used to verify in accord with the three ETV programs. Technology vendors will be required to pay for verification testing for one of the programs. However, costs for extension to the other two verification programs will be covered by the AdvanceETV project. These verifications will serve as pilots to propose mutual recognition processes under the different ETV schemes and, ultimately, for global recognition. Detailed agreements between candidate technology vendors and the AdvanceETV partners will be prepared as a first step under this cooperative verification initiative. Interested vendors should contact one of the following AdvanceETV partners:(Europe) Christian Gron, DHI, at +45 4516 9570 or chg@dhigroup.com; (U.S.) Amy Dindal, Battelle, at +1 (561) 422-0113 dindala@battelle.org; or (Canada) John Neate, OCETA, at +1 (905)822-4133 or jhneate@etvcanada.ca.

Remediating and Monitoring White Phosphorus Contamination at Eagle River Flats (Operable Unit C), Fort Richardson, Alaska: FY07 Data Report. This is the eighteenth annual contract report prepared by researchers from CRREL and other Federal agencies for the U.S. Army Garrison Alaska, Public Works, describing results of research, remediation, and monitoring efforts addressing white phosphorus (WP) contamination in Eagle River Flats, an 865-ha estuarine salt marsh on Fort Richardson, Alaska. Over the five-year period from 1999-2003, full-scale remediation was performed at Eagle River Flats using six remote-controlled pumps to temporarily drain contaminated ponds, allowing the sediments to dry and the WP to oxidize. This effort successfully remediated about 90% of the ponds. More recently, limited remediation using one or two pumps has been conducted to address the remaining few white-phosphorus-contaminated areas (May 2008, 132 pages).
