A mathematical model to optimize the assimilative waste capacity of unconfined aquifers is formulated. The aquifer is to be used conjunctively with surface sources as a source of water supply. Waste waters may be introduced into the ground water aquifer system by either well injection or by basin spreading of waste waters. In the model, three treatment processes are available to reduce constituent concentrations present in the waste waters: (1) dilution; (2) surface treatment of each sonstituent; and (3) the assimilative capacity of the unsaturated and saturated zones of the aquifer system. The total cost for supplying the dilution water and the cost for surface treatment of each constituent is minimized by the model. Portions of this document are not fully legible.
