The U.S. Geological Survey (USGS) publishes a series of manuals describing procedures for planning and conducting specialized work in water-resources investigations. These manuals include methods for analyzing water, sediment, and other samples to determine the presence and concentration of inorganic substances. The manual "Methods for Determination of Inorganic Substances in Water and Fluvial Sediments" is part of the USGS Water-Resources Investigations series and provides detailed procedures for analyzing water and sediment samples. The manual includes methods for determining the concentration of dissolved constituents, total recoverable and total constituents in water-suspended sediment samples, and recoverable and total concentrations in bottom material samples. It also covers the principles of analytical techniques used in water and sediment analysis, including gravimetry, titrimetry, atomic absorption spectrometry, atomic emission spectrometry, colorimetry, electrometry, and ion-exchange chromatography. The manual is divided into sections, each detailing specific analytical methods and procedures. The manual also includes information on quality control, accuracy, precision, and the use of standard reference samples. The manual is updated regularly to reflect new methods and advancements in analytical techniques. The manual is intended for use by USGS personnel and other professionals involved in water-resources investigations. The manual includes over 125 methods for determining 70 inorganic constituents and physical properties of water, suspended sediment, and bottom material. The manual is organized alphabetically by constituent and includes detailed descriptions of each method, including the application, principle of the method, interferences, apparatus and reagents required, analytical procedure, reporting results, units and significant figures, and analytical precision data. The manual is a key resource for water-quality analysis and is used by planners, developers, water-quality managers, and pollution-control agencies. The manual is updated regularly to ensure that the data collected is reliable and standardized. The manual is part of a series of publications that document and make available data-collection and analysis procedures used by the USGS.
