Further Info] The science of waste disposal attempts to predict the long-term geochemical and hydrologic behaviour of a repository, based upon knowledge of the processes involved and the expected environment. The parameters used in the analysis come largely from experiments in the laboratory, including those carried out in situ within AECL’s “Underground Research Laboratory” deep in the Canadian Shield northeast of Winnipeg, Manitoba. Although laboratory tests can also be used to validate the methodology, and thus increase confidence in the predictions made, the long-term results obviously remain unconfirmed due to the time scale involved. Fortunately, verification of the long-term behaviour of significant geochemical and hydrologic processes, in typical repository environments, can be found abundantly in Natur
