This report summarises the results of the research program Environmental studies du-ring 2007. The pilot study regarding environmental security that was performed 2006 has been revised. The revised version has been used for the development of a tentative environ-mental security strategy for the Swedish government. Suggestions for revision of the Armed Forces Environmental management manual have been developed. A Nordic meeting for researchers in defence environmental issues was arranged in Umeå in March. The project for developing sampling strategies for environmental risk assessments is finished and reported. During 2007 field analyses have been performed at the Camp Eagle Base in Bosnia and Herzegovina. Together with the National CBRN Defence Centre a field sampling campaign has been performed. FOI has participated in an in-ternational inter calibration study concerning toxicological characterization of water from waste dumps. The climate chamber and the lysimeters are now fully working with automatic sampling and on line survey. During the fall tests were performed to deter-mine the flow and the infiltration velocities in the lysimeters. A model for the demilitarisation of munitions has been presented. It contains an open strategic demilitarisation plan for the coming 3-5 years. Furthermore it is suggested to set up a committee named DEMIL to ensure the development of documents and com-petence needed. In order to facilitate the introduction of environmental requirements in the acquisition process FOI has introduced methods and solutions to be used by the Defence Material Administration. The methods are presented in a systematic way depending on which environmental effects they include and where in the life cycle they are suited.
