Sample collection is done after well purging. Raw sample bottles are filled directly from <br />the pump discharge tube. Filtered sample bottles are filtered from a triple rinsed plastic <br />bottle. Some sample bottles require filtration to fill the bottles. A peristaltic pump is used <br />to slowly pump the water through a 0.45µm pore size disposable filter. The pump tubing <br />is rinsed with distilled water before and after use. The MW-12, EF-V2, EF-V3A, EF-V4 <br />& EF-AW1 filtration is done at the pump discharge tubing because of the variable flow <br />rate of the Redi Flow II pump. <br />Sample Handling: Sample sets are ordered from the laboratory. They arrive in a cooler <br />with the required paper work and preservatives. Instructions are included for filling <br />bottles, labeling, packing and chain of custody. Labels are filled out for each bottle as to <br />sample I.D., date, time, analysis, preservative and filtration. Sample bottles are labeled <br />and filled in the field according to laboratory instructions. The bottles are cleaned, dried <br />and placed in a cooler with ice. The current sample size is one site per cooler. At the end <br />of each day's sampling a Chain of Custody (COC) document, and over night shipping <br />papers are filled out. Coolers are repacked with all glass bottles bubble wrapped, new ice <br />containers and additional packaging are added so there can be no movement of bottles in <br />the cooler. The shipping papers and COC are attached to the outside of the cooler, and a <br />copy of the COC placed inside the cooler. Coolers are sealed with wrapping tape and <br />tamper proof seals then delivered to Federal Express for overnight shipping. <br />(iv) parameters analyzed, water quality analysis methods, and quality control and quality <br />assurance methods; <br />M-1980-047 Technical Revision 14 Submittal Page 4
