RFSNA Industries Inc. <br /> Piz M4q <br /> Quality Assurancc/Quality Control Plan <br /> Revised November I99'_' <br /> measurements will be taken both before and after purging of each well casing volumes. Once <br /> i the well is purged and indicator parameters have stabilized, a sample will be collected after the <br /> water level approaches 80 percent of its initial elevation. Where water Ievel recovery is slow, <br /> the sample will be collected after stabilization is achieved and enough water is present to fill <br /> sample containers. <br /> Cross contamination from transferring pumps (or bailers) from well to well will be avoided by <br /> === utilizing dedicated equipment_ Where this is not feasible, thorough cleaning of equipment will <br /> be performed between sampling rounds. Sampling will proceed from the least contaminated to <br /> the most contaminated well, if information is available before sample collection,p o lection, or if it is <br /> indicated by field evidence. Where several types of analysis will be performed for a given well, <br /> individual samples will be collected in the following order: <br /> 1. Volatile Organics <br /> 2. Purgeable Organic Carbon <br /> 3. Purgeable Organic Halogens <br /> !` 4. Total Organic Carbon <br /> S. Total Organic Halogens <br /> _. b. Extractable Organics <br /> 7. Total Metals <br /> 8. Dissolved Metals <br /> F' 9. Phenols <br /> ' 10.
