Abstract/Description or Keywords Heterogeneity within the sand and gravel glacial outwash deposits of the AbbotsfordSumas aquifer is investigated using ground penetrating radar (GPR) and borehole geophysical logging. Layering consists of fining upward sequences up to 5 m thick that are continuous over 10’s of metres. Heterogeneity is best represented in a local scale groundwater model using vertical anisotropy based on the relative comparison of model travel times and groundwater ages. The spatial distribution of nitrate provides initial and calibration concentrations for the transport model. Observed concentrations are considerably higher than those predicted by the model.
