However, after the initial demand was met, the industry went into a decline. The combination of a lack of environmental protection legislation and little care being taken to minimize environmental impacts resulted in many sites being abandoned with no thought of remediation. With the advent of nuclear power the industry had a revival during the 1970s and exploration activity surged ahead. New mines were developed, but environmental protection continued to be only an afterthought in the early days of this phase. For newer mines remediation planning became a requirement demanded ever more strongly by the authorities as the community began to express concerns about mining legacies being left for future generations to manage. In the 1990s, two major uranium mine legacy remediation programmes were started up, one in Germany and the other in the USA. It was not long before these two groups began communicating, sharing ideas and problems with a view to exchanging data and experience in order to optimize project implementation and improve outcomes in the two countries. In 1993, a first meeting was held in the USA which the experts from both the initial partner countries found very rewarding as a means of peer review and data exchange. Further meetings followed and by 1995 invitations to participate had been extended to other groups working on similar issues in Canada and South Africa. About this time the group acquired a name — the Uranium Mining Remediation Exchange Group (UMREG). The group had no formal funding and organization was undertaken by volunteers. The group has continued to try and meet annually, usually within the framework of a larger conference or symposium which was willing to allow UMREG to ‘piggy-back’ on their organization. By the early 2000s, much of the early work was coming to an end and there seemed to be little prospect of new activity until the funding for the remediation of other legacy sites became available. Consequently, the UMREG Executive Committee decided to assemble a selection of papers from UMREG meetings, update them where appropriate, and solicit additional invited contributions. The idea was to ensure that the accumulated knowledge would be preserved for future use. This publication has been put together by UMREG, in consultation with the IAEA, initially as a summary record of past remediation activities. However, given the boom in uranium mining that began in 2004, it is now seen as a resource for those countries looking to remediate legacy sites in the course of redeveloping old uranium resources or for countries seeking to establish uranium mining industries and wishing to avoid the errors made previously. In both cases this publication is intended to show what lessons have been learned, from both mistakes and successes, in the business of remediating uranium mines, and to showcase potential ways forward to reduce the risk of new legacy sites being created. The IAEA wishes to acknowledge the significant efforts of the UMREG Executive Committee: A.T. Jakubick, P.W. Waggitt and D. Metzler. The IAEA officer responsible for this publication was R. Edge of the Division of Radiation, Transport and Waste Safety.
