Pollution from rural, transportation, extractive, and undisturbed land uses in the Grand and Saugeen Watersheds
The effects of land drainage from rural land use, transportation corridors, extractive operations and undisturbed (under perennial vegetative cover) areas on the receiving water quality in the Grand River and Saugeen River pilot watersheds (Ontario) were investigated as part of the Task C activities under the Pollution from Land Use Reference Group (PLUARG) of the International Joint Commission. Water-quality and water-quantity data were collected during 1975 and 1976 from: eight rural watersheds; upstream and downstream of a major highway corridor, a sand and gravel pit, a limestone quarry and; from two relatively undisturbed (wooded/idle) land areas in the Grand River and Saugeen River pilot watersheds. Based on the analysis of the data over a two-year period (1975-1976), the major sources of pollutants from these different land uses have been tentatively identified as follows: rural land uses, transportation, extractive operations, and undisturbed (wooded/idle).
