Whetstone Associates has extensive experience preparing, calibrating, and defending numerical ground water flow and contaminant transport models.  We have developed numerous models for water supply, mine dewatering, evaluation of remedial design, determination of probable impacts, and permitting support.  We employ state of the art modeling techniques and statistical analysis, and can provide high quality graphics for litigation support, public meetings, and presentations.

We also develop unsaturated flow models to evaluate infiltration for cap/liner systems associated with landfills, hazardous waste sites, leach pads, waste rock dumps and reclaimed facilities.  We use a variety of modeling codes including HELP3, UNSAT-H, Soil Cover, and VS2D and can tailor the modeling approach to fit the requirements of your site.
