The National Field Manual for the Collection of Water-Quality Data (National Field Manual) describes protocols and provides guidelines for U.S. Geological Survey (USGS) personnel who collect data used to assess the quality of the Nation's surface-water and ground-water resources. This chapter of the manual addresses the selection of equipment commonly used by USGS personnel to collect and process water-quality samples.
Each chapter of the National Field Manual is published separately and revised periodically. Newly published and revised chapters will be posted on the World Wide Web on the USGS page 'National Field Manual for the Collection of Water-Quality Data.'
