The vacuum in the sample ampoule draws groundwater through the tip <br />into the glass ampoule, The glass ampoule is then pulled out of the pipe, disengaging the <br />syringe. The septum in the glass ampoule and drive tip rescals after the syringe, is removed. <br />G Mr -W '171 <br />73,0H IWFV%7k, P57 - <br />ililiple., and other equipment used for sample collection are stearn cleaned and/or washed with <br />trigodium phosphate or non -phosphate detergent solution and double rinsed with distilled watex <br />prior to use. The satriple probe and filters are cleaned in TSP solution and rinsed with mcthyl <br />alcohol followed by a distilled water rinsc prior to use. New, factoty-sterilized syringe needles, <br />0 -rings, septum's and sample tubes are used for each sample. <br />B -M Sample Handling <br />After labeling, the sample is immediately stored in an iced cooler for transport to Kleinfeldee's <br />office sample, control or to the analytical laboratory. A Kleinfeldcr chain -of -custody forin <br />accompanies the cooler. The chain -of -custody fbm includes K16nfeldees name, addym and <br />telephone number, the ernployee number of the individual who performed the samplin& the <br />the samoutes were collected the number of containers each <br />sample occupies, the sample matrix (soil or water) and the analysq for which the samples are <br />being submitted, if any. The chain -of -custody form is signed by each person who handles the <br />samples, including all Kleinfelder empk)ym and the recciving employee of office sample <br />control or the analytical laboratory when the samples am delivered. <br />0 =1 <br />To reduce the potential for cross -contamination, augers and associated equipment am steun <br />cleaned prior to drilling each buring. In addition, sampling equipment is cleaned with 9L <br />trisodium phosphate or non -phosphate detergent wash and rinsed with distilled water prior tft <br />collecting each soil sample. <br />20-YPI-611WIPIA3 Pap 8.3 <br />Copyright 2001, Kleintelder, Im Jurve 14, 2041 <br />
