The Northeastern Soil Survey was conducted during 1985 as a synoptic physical and chemical survey to characterize a statistical sampling of watersheds in a region of the United States believed to be susceptible to the effects of acidic deposition. The document addresses the implementation of a quality assurance program and the verification of the analytical data base for the Northeastern Soil Survey. It is focused primarily towards the users of the data base who will be analyzing the data and making various assessments and conclusions relating to the effects of acidic deposition on the soils of the Northeastern region of the United States. Verification procedures used to analyze laboratory data are described. Quality is assessed by describing the detectability, precision, accuracy (interlaboratory differences), representativeness, completeness, and comparability of the data for the quality assurance samples used throughout the soil survey.
