This three dimensional model illustrates a hypothetical UST site. The water table and bedrock are shown as mesh surfaces, constructed from subsurface investigation report results. Vadose zone VOC concentrations are illustrated via slice overlay, and show localized, and downward decreasing impacts. Colors are keyed to regulatory action levels. Locational control is supplied by site specific coordinate system on x, y, and z axes, and by street names.
