There is a small pond in Crawford County, Ill., which provides the habitat and primary food source for several different species of fish, frogs, turtles, insects, and birds, as well as small mammals. About a half-mile away is the Jack J. Ryan and Sons Manufacturing Company. For years, this plant has safely treated its wastewater—produced during the manufacturing process—and discharged it into the pond. Then one day, without warning, hundreds of dead fish wash up on the banks of the pond. What's going on? What should be done? It is the job of environmental engineers to investigate and design a system to make the water safe for the flora and fauna that depend on it for survival.
