Agricultural pollution of the Great Lakes Basin - Combined report by Canada and the United States
This report is intended to be a State-of-the-Art document concerning abatement of pollution of the Great Lakes Basin, as specifically influenced by agricultural and related sources. It was compiled by technical personnel, from appropriate fields in universities and governmental departments in Canada and the United States. Primarily it relates to the identification of the impact of agricultural and related activities on the pollution of the Great Lakes Basin. The major constituents of these non-point sources of pollution which were studied included: 1) runoff and release of nutrients, pesticides, and herbicides and degradation by-products as a consequence of the application of agricultural chemicals, 2) runoff of pollutants from animal and poultry production operations and from associated animal waste management structures and lands used for ultimate disposal, 3) sedimentation resulting from current land use practices, including land influenced by agricultural activities and by local, state and federal activities on public lands, highways and parks. Also under study was the scope of current planning, advisory and regulatory functions of the United States and Canadian Governments. The findings of some of the basic research conducted to date by both Nations, and the substance of the programs of the numerous regulatory agencies involved, are presented in this text. Its purpose is one of motivating development of more comprehensively effective and universally applicable methodology for the management of wastes from agricultural and related activities, and the amelioration of the invaluable water resources throughout the Great Lakes Basin.
