Y <br /> 3 <br /> 1. U.S. Environmental Protection Agency (EPA) and State certifica- <br /> tion programs. <br /> 2. Participation on an interlaboraLory or "round-robin" quality as <br /> surance program. <br /> 3. Verification of results with an alternative method. For example, <br /> calcium may be determined by atomic absorption, ion <br /> chromatography, or titrimetric methods. volatile organics may be <br /> determined through either purge and trap or liquid-liquid <br /> extraction methods. <br /> - 3.4 Miscellaneous Checks of Accuracy <br /> Where trace analysis is involved, purity of the solvents, reagents and <br /> gases employed is of great concern. The laboratory maintains a service <br /> contract on all major instrumentation; gas chromatograph, atomic <br /> absorption, ion chromatography, and total organic carbon analyzers are <br /> all serviced and maintained regularly. <br /> The aboveprogram is more than sufficient for most needs. Additional i <br /> quality assurance such as spikes and duplicates on all analyses, wiil <br /> be provided if requested. <br /> W. <br /> J - <br /> MINN <br /> ;j <br /> a <br />
