Includes bibliographical references. "While effects of acidification of natural waters in Nova Scotia from acidic precipitation have been, and continue to be, documented, there is also evidence to indicate acidification from anthropogenic activities occurring in areas underlain by mineralized slate bedrock. The purpose of this study has been to document, for an area of Nova Scotia underlain by bedrock of the Meguma Group, the risk of acidification from anthropogenic activities and to check this risk designation using available water quality information. The defined study region incorporates Queens County, the Municipality of Lunenburg, and the portion of Annapolis County encompassed by Kejimkujik National Park"--Executive summary, page i.
