Description:
A two phase study was conducted to develop a synthetic suspended solids sample for use as quality control check and performance evaluation within environmental monitoring laboratories. The first phase consisted of a feasibility study to determine compounds that exhibited the optimum physical and chemical properties for synthetic suspended solids samples, and the second phase involved production of suspended solids samples in individual containers. Compounds investigated that met all the design criteria included rayon fibers and Fuller's earth. A total of 10,000 quality control samples consisting of rayon fibers, Fuller's earth and anthracite coal were packaged for completion of the project. Anthracite coal was packaged to demonstrate the variability in the subsampling step of the suspended solids test method with certain types of solids. This report was submitted in fulfillment of Contract Number 68-03-2333 by Roy F. Weston, Inc. under the sponsorship of the Office of Research and Development, U.S. Environmental Protection Agency. Work was completed in April 1976.
