Laboratory Analysis

Water Quality Parameters

The MOU Group collects water samples for a variety of laboratory analyses. Table 4-5 lists the water quality parameters analyzed (analytes), agencies conducting the sampling, and the title of any documents describing specific sample collection procedures for that analysis; documents listed can be found in Appendix D (or by following the hyperlinks from the “Analytical Sampling Matrix” located in Appendix C). Parameters not listed in this table indicate there is not a specific agency-defined protocol for field sample collection of that specific analyte.
