Contents Notes
The Direct/Delayed Response Project was designed to address the concern over potential acidification of surface waters by atmospheric sulfur deposition in the United States. The purpose of these synoptic soil physical and chemical surveys was to characterize watersheds in regions of the United States believed to be susceptible to the effects of acidic deposition. This document describes the implementation of a quality assurance program and the verification of the analytical data base for the Mid-Appalachian Soil Survey. It is directed 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 watersheds of the region. The results show that the measurement quality objectives for detectability, precision, accuracy, representativeness, and completeness were generally satisfied. Measurement uncertainty was generally low in relation to overall data uncertainty. A series of conclusions and recommendations are provided at the end of the report. The recommendations will be useful in the planning of future projects of this nature.
