Field operations and quality assurance/quality control for Direct/Delayed Response Project soil-mapping activities in the Southern Blue Ridge Region

The Direct/Delayed Response Project is a three-level program designed to address concern over potential acidification of surface waters by atmospheric deposition within the United States. The mapping phase of the Southern Blue Ridge Region soil survey was conducted during the fall and winter of 1985-86 to characterize spatial distribution of soils, land use, vegetation, depth to bedrock, and lithology of 35 watersheds thought to be susceptible to acidic deposition. The document describes planning activities and summarizes field operations and quality assurance/quality control activities associated with mapping of the region.
