<br />020, Revised 1983: (Methods for Chemical Analysis of Water and <br />~ Wastes). A list of these methods and their applicable method <br />numbers is given as Appendix C. <br />5.3 Quality Control <br />' , The details of the quality control procedures to be used by the <br />analytical laboratory are contained in their standard operating <br />procedures (SOP), the relevant parts of which are pYesented in <br />Appendix A. These quality control procedures are baffied on, and <br />developed from, the principles described in Chapter 1, USEPA/OSWER <br />SW-846 (1986, 3rd Edition). <br />' Appendix A includes descriptions of protocols for the analysis of <br />reference standards, matrix spiking and recovery analyses, analysis <br />' of duplicate samples, and analysis of field and rinsAte blanks, <br />together with methods for the assessment of the data so generated. <br />Appendix D gives the limits required under the analytical <br />laboratory quality control procedures for: <br />' (1) Upper and lower acceptance methods for analysis of <br />' reference standards for each analytical parameter and for <br />each analytical method; <br />(2) Upper and lower acceptance limits for matrix spiking <br />recovery analyses for each analytical parameter and for <br />' each analytical method; <br />' (3) The upper limit for the relative deviation between <br />duplicate analyses for each analytical parameter and for <br />each analytical method; and <br />-32- <br />1 <br />
