El <br />Following retrieval, both ends of the brass liner will be covered with Teflon, securely <br />• <br />capped with polyethylene end caps, labeled, and placed in an ice chest containing Blue Ice <br />and kept at 4 ° C for transport to the analytical laboratory for chemical analyses. <br />• If soil samples cannot be safely collected from the excavation, soil samples will be collected <br />using the backhoe. Immediately upon removal of the tank, a backhoe bucket of native soil <br />from each sample location will be taken. After filling the backhoe shovel from the desired <br />• location in the bottom of the excavation, a large solid chunk of soil will be chosen for <br />sample collection. Using a hand trowel, approximately 6 inches of soil will be rapidly <br />scraped away from the surface of the soil. Soil samples will then be collected as previously <br />• described. <br />Water samples will be collected using a disposable bottom -entry polyethylene bailer. The <br />collected sample will be transferred into a 40 -milliliter VOA vial with as little aeration as <br />• possible, and allowing no headspace in the vial. A Teflon septum inside the vial's cap will <br />0 <br />be used to seal the vial. The collected sample will be labeled and placed in an ice chest <br />maintained at 4 ° C for transport to the analytical laboratory for chemical analyses. <br />All samples collected will be labeled with the sample identifier, location, sampler's name, <br />time and date of sample collection, and analyses requested using a black indelible marking <br />• pen. All samples collected will be recorded on a Sample Management/Chain-of-Custody <br />form which will track the sample from time of collection to delivery at the analytical <br />laboratory. All information recorded on the Sample Management/Chain-of-Custody form <br />• will be entered in ink. <br />Before and after each subsequent soil and/or groundwater sampling event, all sampling <br />equipment will be cleaned. Cleaning will consist of removing solid material from the <br />i sampling equipment using clear water and plastic bristle brush, washing the sampling <br />equipment in a mixture of clear water and Liqui-Nox or Alconox (the use of phosphate <br />h1pbe•12(da4) <br />U <br />
