Health and environmental chemistry: analytical techniques, data management, and quality assurance. Volume 1

This section of the manual has been prepared to document the analytical methodology used by the Los Alamos National Laboratory Health and Environmental Chemistry Group. It is part of the overall quality control effort to support the health, safety, and environmental programs at the Laboratory. The section provides analytical methods for the monitoring of waste discharges under the National Pollutant Discharge Elimination System. The analytical procedures were developed by the Health and Environmental Chemistry staff, were modified from standard methods developed and evaluated by the Environmental Protection Agency (EPA), or were adapted from procedures found in the literature. The procedures have been tested by chemists and technicians to prove their validity. The methods measure the concentration of the desired analytes with the precision, accuracy, and specificity required by Group HSE-7, Waste Management, and meet the needs of federal legislation. The procedures utilize equipment and skills available in modern waste water chemistry laboratories. Precision and accuracy statements are provided where such data are available. Each procedure is presented in a simple and concise manner and includes interferences, apparatus, reagent preparation, calibration methods, and data reduction formulas.
