Abstract

This report summarizes information, guidelines, and minimum requirements that apply generally to the seven field-measurement sections that comprise the rest of Chapter A6 of this U.S. Geological Survey (USGS) National Field Manual for the Collection of Water-Quality Data (NFM). Protocols are specified for establishing and maintaining data records, use of field-measurement instruments and methods, and quality assurance of data-collection and reporting methods that are relevant to surface-water and ground-water field-measurement activities.
