Abstract:

A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the pulse injection of two inorganic tracers and five halogenated organic chemicals. The data is presented as a case study in modeling variograms and cross-variograms including the case where some variables are under-sampled. Co-kriging allows the interpolation and hence contouring incorporating both spatial and inter-variable correlation. Numerical results are presented comparing results obtained by other methods and co-kriging.
