AbstractThe Discrete-State Compartment (DSC) model was used to model water quality in a hypothetical valley in the southwestern United States. The objective was to predict water quality changes over a 100- year period due to changes in pumping scenarios over that time period. Total dissolved solids (TDS) were used as an indictator of the change in water quality. The system was modeled using 82 compartment (cells) based on the groundwater pattern as modeled by the McDonald-Harbaugh groundwater flow model (MODFLOW). Trends in the concentration of TDS were graphed for specific cells. These trends showed a diminishing of water quality in all scenarios.
