“…Most earlier efforts to determine patterns of surface water sensitivity to acidic deposition have relied on interpretations of bedrock distribution and chemistry (Galloway and Cowling 1978, Likens and others 1979, Hendry and others 1980, National Atmospheric Deposition Program 1982. One effort was based on soil sensitivity (McFee 1980) and another on surficial geology (Shilts 1981).…”

/ This map (see the inside back cover of this issue) illustrates the regional patterns of mean annual alkalinity of surface water in the northern portions of Minnesota, Wisconsin, and Michigan, USA. It provides a qualitative graphic overview of the relative potential sensitivity of surface waters to acidic input in the upper midwest portions of the United States. The map is based on data from approximately 14,000 lakes and streams and the apparent spatial associations between these data and macroscale watershed characteristics that are thought to affect alkalinity.

“…Large areas in the eastern United States are at risk with respect to the depletion of basic cations [Galloway and Cowling, 1978;Federer et al, 1989]. In regions where silicate weathering is dominant, weathering inputs may not be sufficient to replace the accelerated losses of basic cations associated with disturbances such as acidic deposition or intensive forest harvest.…”

Abstract. Depletion of Ca in forests and its effects on forest health are poorly quantified. Depletion has been difficult to document due to limitations in determining rates at which Ca becomes available for ecosystem processes through weathering, and difficulty in determining changes in ecosystem storage. We coupled a detailed analysis of Sr isotopic composition with a mass balance at Cone Pond Watershed, New Hampshire, in order to further constrain estimates of these processes. Strontium acted as an analog for Ca in most processes except translocation of nutrients within forest vegetation. Variability in mineralogic and Sr isotopic composition of bedrock and soils complicated assessment of 87 8-6the Sr/ Sr ratio released to solution by weathering reactions. By conducting a mass balance on atmospherically derived Ca, it is possible to distinguish Ca weathering losses from Ca leached from ecosystem pools. The calcium weathering rate estimated by this method was less than half of that determined by mass balance assuming steady state conditions.

“…The potential of acid deposition to alter soil chemistry in susceptible regions of the country [milestone 7] was identified in several papers at the First International Symposium on Acid Precipitation and the Forest Ecosystem (Dochinger and Seliga 1976) and by Galloway and others (1976). Fuller development of the concept of regional sensitivity based on geological sensitivity was presented by Galloway and Cowling (1978).…”

/ Scientific quality in a technical policy document is defined in terms of the proportion of contemporary scientific principles on a subject that the document competently discusses. As a case study of the scientific quality of such documents, this articles examines the treatment of acid deposition effects in 126 environmental impact statements on fossil-fuel power plants. On average, the relevant environmental statements cover only a quarter of the eligible scientific principles. Bureaucratic and political factors influence the quality of discussion of acid deposition more than do strictly objective or scientific factors. In particular, public participation and interagency review processes foster relatively thorough consideration of scientific information in environmental impact statements.
