Approximately 3 inches of soil were scraped away from the surface of this soil A clean <br /> brass tube installed within a clean sample corer (with attached slide hammer) was driven into <br /> the soil Figure 4 shows soil sampling locations <br /> Upon extraction, each soil sample was checked for the presence of petroleum hydrocarbons, <br /> and promptly sealed with aluminum foil, plastic end caps and tape The samples were then <br /> placed in a "ziploc" bag, sealed with security tape and stored in an ice chest with water ice <br /> until delivery to the on site laboratory Cham-of-custody records were maintained for all <br /> samples (Appendix A) <br /> 4.3 Stockpile Soil Sampling <br /> Four composite soil samples were collected from the excavated soil The samples were <br /> collected at least two feet beneath the pile/bin surface, using a sample corer with attached <br /> slide hammer The sample corer were contained a 2" x 6" decontaminated brass sleeve for <br /> collection of undisturbed samples Upon extraction, the samples were checked for the <br /> presence of petroleum hydrocarbons and promptly sealed with aluminum foil, plastic end <br /> caps, and tape The samples were placed in a "ziploc" bag sealed with security tape and <br /> stored in an ice chest with water ice until delivery to the selected laboratory Chain-of- <br /> custody records were maintained for all samples <br /> 4.4 Soil Sample Analysis <br /> The samples were analyzed by DOHS certified onsite mobile laboratory, utilizing the methods <br /> and detection limits shown below <br /> Analysis Name Method Detection <br /> Limit (ppm) <br /> BTEX EPA modified 8020 0005 <br /> (benzene, toluene, ethylbenzene, total xylenes) <br /> TPH as diesel DHS GC-FID modified 1 <br /> 8015 <br /> Note <br /> TPH = Total Petroleum Hydrocarbons <br /> MZ/01-27-95/UST/95-0011 nbr 4 <br />
