5. Environmental impact of pig wastes

This chapter details the physical, chemical, and biochemical properties of wastes as excreted and collected in PFA "wastewatersheds." It also describes an assessment of the environmental impact of pig wastes discharged into estuaries from the wastewatershed of two PFAs. The question and answer portion of the chapter is intended for those uninitiated in the concepts of pollution-measuring parameters. However, it also includes data on metals and other chemical elements plus numerous measurements of the numbers of bacteria and fungi found in pig wastewaters at various stages of treatment.
