Groundwater contamination at a hazardous waste site near Pullman, Washington is simulated by a numerical model. The aquifer at the site is classified as an unconfined valley aquifer. Solute transport was found to be towards the aquifer outlet, Airport Creek. The model predicts initial trace contaminant, by a nonreactive solute, at the node representing Airport Creek six to 11.4 years after the start of the simulation. This simulation of a nonreactive solute transport represents a worst case scenario. Results are presented and discussed in a context to prevent future groundwater contamination.
