Description EPA-VHS is a screening level model to predict maximum concentration of a pollutant at a prescribed distance downstream from a continuous source (at the compliance point). The model is based on an analytical solution for the transport of a conservative constituent in a homogeneous, isotropic aquifer with 1D horizontal, steady-state flow and dispersion perpendicular to the flow path. The model assumes zero retardation, a continuous input source, and saturated conditions. The program package contains two versions: 1) the modified EPA version as published in the Federal Register, 50 FR 48886, November 27, 1985; and 2) the original VHS model as published by Domenico and Palciauskas in Ground Water, Vol. 20, No. 3, pp. 301-311, 1982. Menu-driven with interactive data entry and editing. The program can be used with either metric or US customary units. Results are displayed on screen in tabular format.
