This study is an attempt to further understand the process by which industrial organizations change the way they dispose of waste. Substantively, the relationship of organizational characteristics to rates of change in waste procedures is of interest. A general model of change is envisioned. The two major forces creating change in industrial organizations are the internal pressures within the organization that result from such factors as the complexity of its division of labor and production technology, and the kinds of pressure the organization faces as the result of powerful and aggressive regulatory agencies and other groups. Finally, the nature of dependence the firm has upon water affects change. (Modified author abstract)
