Description SUMMERS is a screening level interactive computer program for estimating soil cleanup levels. The model assumes that a percentage of rainfall at a polluted site will infiltrate and desorb contaminants from the soil based on equilibrium soil-water partitioning. Using a mass balance approach and assuming equilibrated, complete mixing in the aquifer, the soil cleanup level is calculated from the original soil concentration, the concentration of the infiltrating water, and an equilibrium coefficient. Developed to estimate when contaminant concentrations in the soil will produce aquifer contaminant concentrations above acceptable levels. The resulting soil concentrations can then be used as guidelines in estimating boundaries or extent of soil contamination by applying the derived maximum soil contaminant concentration level to the observed concentration in the soil at the site. Menu-driven, interactive code and includes simple error-checking. Produces tabular on screen results.
