Among the more serious problems in transport of wastewaters is                  the rapid corrosion of concrete interceptors in large collection                systems.  The progress of such corrosion is driven by the                       evolution of hydrogen sulfide gas followed by its reoxidation in                the aerobic crown with accompanying acid production.  Both steps                are microbially catalyzed.  Consequently, the process may be                    interrupted by appropriate engineering measures designed to                     suppress the activity of sulfate reducers or acidophilic                        autotrophs in the conduit's crown.  Such measures will be                       explored within the proposed project.  Candidate actions,                       including chemical control in the liquid phase and pH control in                the crown can be economically investigated in a bench-scale                     laboratory program.
