Techniques of Water-Resources Investigations of the United States Geological Survey

Techniques of Water-Resources Investigations of the United States Geological Survey

1989 | Marvin J. Fishman and Linda C. Friedman, Editors
This chapter, "Methods for Determination of Inorganic Substances in Water and Fluvial Sediments," is part of the U.S. Geological Survey's series on techniques for water-resources investigations. It provides detailed methods for analyzing water, suspended sediments, and bottom material for inorganic constituents. The chapter covers over 125 methods for determining 70 inorganic constituents and physical properties, including dissolved constituents, total recoverable and total inorganic constituents in water-suspended sediment samples, and recoverable and total concentrations in bottom material samples. It includes definitions, quality control procedures, and a discussion of the accuracy and precision of analyses. The chapter also outlines the principles and specific applications of various analytical techniques, such as gravimetry, titrimetry, atomic absorption spectrometry, and atomic emission spectrometry. Each method is described in detail, covering application, principle, interferences, apparatus, reagents, procedure, reporting results, units, significant figures, and analytical precision data. The chapter emphasizes the importance of standardization, quality assurance, and the use of reference materials to ensure the reliability and comparability of analytical data.This chapter, "Methods for Determination of Inorganic Substances in Water and Fluvial Sediments," is part of the U.S. Geological Survey's series on techniques for water-resources investigations.
