L <br />' tare so.~ rat rush - ~~ saytoq nwoed <br />' Soil Sampling <br />' Stoclcpt7e and pipechase excavation grab sort samples wt11 be collected by hand digging <br />into each location to obtain sort which was not exposed or in contact with equipment Each <br />sample will be immediately placed is a clean, properly labeled glass sample jar with no <br />' observable tread space and placed on ice to lower its temperature to less than 4•C. Gloves <br />will be worn and changed prior to the collection of samples at each ittterval to prevent <br />possible aoss-contamination. <br />While conducting the dnlliag of boreholes, discrete soil samples will be collected <br />according to standard industry practices with either continuous tube or split spoon samplers. <br />' Prior to each rue, the sampling devices and angers wIll be decontaminated using a hot water, <br />high pressure spraying system or a similar method rued for bat7er decontamination. <br />' Each soil sample col]ected wt71 be divided upon retrieval. One portion w1~ be <br />immediately sealed in a clean, glass sample jar with no head space and immediately cht7led <br />' to less that 4 • C. All samples collected for potential laboratory analyses of hydrocarbon <br />concentrations wt11 remain chilled and, if chosen for laboratory analyses, wt71 be analyzed <br />within founeen (14) days of collection. The remaining portions of the split sot? samples will <br />be field-saeened for contaminant vapors to provide support data to determine which <br />samples wt11 be submitted for laboratory analyses. Samples wt11 also be properly logged to <br />determine sot? types and Iithologies. Information regarding the type of vapor analysis, the <br />' instrument's cahbration, and the method urilized wt71 be recorded. <br />1 <br />1 <br /> <br />1 <br />1 <br />1 <br />' -9- tword taaaA~ <br />
