In this paper, applications of linear goal programming techniques to the analysis of design, management and operational problems in the deep-well injection industry are investigated. Deep-well injection is a method of hazardous waste disposal where liquid or liquefiable wastes are pumped under controlled rate and pressure into confined formations that have no other potential use. A typical liquid waste injection system is modeled as a linear goal program to study and resolve the effects of conflicting objectives such as cost, environmental regulations, equipment utilization and waste-water quality requirements before injection. The model is validated using actual data obtained from a waste-water disposal complex in Odessa, Texas. The goal program is solved for the best disposal system design and operating policies that would not only enable the plant to meet the Environmental Protection Agency's standards, but best minimize capital investment, annual operating expense and deviations from the waste-water quality requirements before injection. Justification of the use of the model is presented by comparing the actual design and operating policies of the system with the optimal design obtained from the solution of the model. This comparison showed 40% savings in favor of the design predicted by the model.
