Guide to the Application of Quality Assurance Data to Routine Survey Data Analysis

摘要

The National Surface Water Survey of the National Acid Precipitation Assessment Program was designed to evaluate the present status of the nation's surface waters with regard to the problem of acidic precipitation. The report provides assistance in utilizing the quality assurance data when interpreting the routine survey data. The quality assurance reports for each of the surface water surveys, Eastern Lake Survey - Phase I, Western Lake Survey - Phase I, National Stream Survey - Phase I and Eastern Lake Survey - Phase II provide detailed information on the detectability, accuracy and precision of the routine lake data collected within each of these surveys. The data contained in the quality assurance reports pertaining to each of these issues can provide additional information which can enhance the analysis of the routine lake data and extend the applicability of the survey data beyond the original intent by providing future investigators the kind of detailed information about the quality of the data which is necessary when applying the data to studies for which it was not designed.
