Environmental Protection Agency protocols sample analysis

A good example of a prescriptive approach to quality assessment is the protocol outlined in Figure 15.2, published by the Environmental Protection Agency (EPA) for laboratories involved in monitoring studies of water and wastewater. Independent samples A and B are collected simultaneously at the sample site. Sample A is split into two equal-volume samples, and labeled Ai and A2. Sample B is also split into two equal-volume samples, one of which, Bsf, is spiked with a known amount of analyte. A field blank. Dp, also is spiked with the same amount of analyte. All five samples (Ai, A2, B, Bsf, and Dp) are preserved if necessary and transported to the laboratory for analysis.

The U.S. Environmental Protection Agency has established a manual of Test Methods for Evaluating Solid Waste (SW-846) to provide a unified source of information on sampling and analysis related to compliance with the Resource Conservation and Recovery Act (RCRA). This manual provides methodology for testing representative samples of waste and other materials to be monitored. Methods 8150 and 8151 of the SW-846 manual both present protocols for determining certain chlorinated acid...
