Excerpt
WHAT is the sensitivity of the nation's lakes and streams to acidification (19)? Early efforts to determine such sensitivity relied on interpretations of bedrock distribution and chemistry (11, 17, 24, 30). Other efforts were based on soil sensitivity (28) and surficial geology (39).
Although these studies contributed to the general knowledge about the extent of surface water sensitivity, their results sharply disagree, from one portion of the country to another. More importantly, there is a lack of spatial correlation between the patterns drawn by these efforts and the observed patterns of surface …
