Example: Setup of models for a field site (Akacievej, Hedehusene)
DRAFT will be completed soon
First, several models are compared for a contaminated site in Denmark, where a plume of dissolved PCE has migrated through a fractured limestone aquifer. Numerical modeling was integrated in the planning of field tests and in the update of the conceptual model. Field data includes information on spill history, distribution of the contaminant (multilevel sampling), geology and hydrogeology. To describe the geology and fracture system, data from borehole logs, packer tests, optical televiewers and cores was combined with an analysis of local heterogeneities and data from analogue sites. A pump and tracer test with contaminant sampling was performed at the site to determine flow and transport parameters of the fractures and matrix and to quantify the contaminant distribution in the aquifer. Different models were used for the planning and interpretation of the pumping and tracer test.
