Soil Boring Log <br /> The soil boring log is kept by the field geologist. Its primary function is to record lithological <br /> information. However, it is secondarily used to record the depths where samples were collected <br /> field screening information(FID and/or PID readings), and the boring/samplings location number. <br /> Chain-of-CustodX <br /> The samples collected for chemical analysis are usually handled by the crew. leader. This <br /> individual seals the sample sleeves, prepares the sample label and fills out the sample chain of <br /> custody form. The chain of custody forms include the boring/sampling. <location_numbers, the <br /> individual sample numbers, the analyses to be preformed on the sample, the date and time that <br /> each sample is collected, any FID and PID readings, and relavent comments about the sampling. <br /> CChain-of-custody will be maintained to the point at which the laboratory accepts the-samples. All <br /> samples are.checked for integrity and compared with the chain of custody for completeness. The <br /> laboratory will then log each sample into their laboratory management system and -assume <br /> custody of the samples. All samples collected will be received at the laboratory within 24 hours <br /> of collection. I <br /> Daily Work Log <br /> A daily work to is used to record and summarize all of the site investigation work-completed <br /> L y g g P ' <br /> each day. It will.include the following information:.(1) the names of.the personnel on-site, (2). <br /> equipment in use, (3) materials used, (4) waste generation information, (5) the boring/sampling <br /> ' location numbers, and(6) the quantity and depths of samples collected. <br /> Drum Inventory Form <br /> An additional form is used to -document and track investigation derived wastes es (IDV ) during <br /> environmental assessment. Soil cuttings are generated by the drilling activities and wastewater is <br /> generated by the equipment decontamination activities. These wastes are stored in 55-gallon <br /> drums, which must be stored on-site pending disposal. The project",support team will fill-out a <br /> drum inventory form as they collect each drum of soil cuttings and decontamination water. <br /> L' C-5 <br />
