"Concern has been growing over the acidity of atmospheric precipitation in Canada, and in 1977 the Canadian Network for Sampling Precipitation (CANSAP) was established. Cumulative samples of wet precipitation are shipped each month to Department of Environment Water Quality Branch Laboratories at the Canada Centre for Inland waters for analysis. Early results (Figure 1) show that the highest levels of acid precipitation loading are concentrated over the St. Lawrence Valley in Ontario and Quebec, and extend as far as Labrador and the Atlantic Provinces. Concern for the effects of such precipitation on surface waters has led to a compilation of data from various sources to permit identification of the vulnerable areas of eastern Canada "--Page [1].
