Current pollution control practices in the united states

An overview of pollution control practices in the United States is presented here, with particular emphasis on those factors which motivate and direct current practices. A more in‐depth discussion is provided of certain areas, particularly those items which might be unique to the USA. More emphasis has been placed on wastewater‐related issues. The largest dollar expenditures and technical efforts have probably gone to solving these problems in the oleochemical field. Some example projects are presented to demonstrate the significant points.
