Initially, a small vacuum type sidewalk sweeper was used to obtain the samples. Previous studies of water pollution have focused on the effluent of the system, using the given observed pollutional load at the outfall of the sewer system to determine the optimal least cost, in this situation combination of pollution control facilities in order to meet a specified water quality management objective.
The film asks the question: The film employs the Story of Stuff style to tell the story of manufactured demand — how you get Americans to buy more than half a billion bottles of water every week when it already flows from the tap.

Since water is always circulating through the environment, it transports the pollutants it contains from one area to the next. The purpose of the above discussion is to point out the fact that control of urban storm water runoff must be consistent with the long-range objective of determining the optimal waste management program by giving simultaneous consideration to the land; air, and water resources of the area.
