The impetus for the Soil and Water Environmental Enhancement Program (SWEEP) program was the Canada-U.S. Great Lakes Water Quality Agreement, calling for a reduction in phosphorous pollution in the Lake Erie basin of 2000 tonnes per year.

Canada agreed to reduce phosphorous run-off by 300 tonnes per year -- 200 from agricultural cropland sources and 100 from industrial and municipal sources by 1990.

The achievement of these reductions over five years would improve water quality for drinking, recreation and fishing. Improved soil conservation practices to reduce phosphorous run-off would benefit farmers greatly in crop yield increases and in cost savings from more efficient soil management.

In order to accomplish the program objectives, Canada and Ontario carried out five year programs of coordinated and complementary activities with farmers, farm and other organizations. These programs were intended to build up a stock of technology that could be extended to farmers now and in the future.
