APPENDIX II • SOIL SAMPLING PROCEDURES Sort samples will be collected in 3- to 6-inch long brass liners using a drive-tube type sampler which will be driven into the ground using a rubber mallet The sampler will be sufficiently driven into the soil profile so as to allow no headspace in the brass liner Following retrieval, both ends of the brass liner will be covered with Teflon, securely capped with polyethylene end caps, labeled, and placed in an ice chest containing Blue Ice and kept at 4 G C for transport to the analytical laboratory for chemical analyses If soil samples cannot be safely collected from the excavation, soil samples will be collected f using the backhoe A backhoe bucket of native soil from each sample location will be taken After filling the backhoe shovel from the desired location in the bottom of the excavation, a large solid chunk of soil will be chosen for sample collection Using a hand trowel, approximately 6 inches of soil will be rapidly scraped away from the surface of the soil Soil samples will then be collected as previously described All samples collected will be labeled with the sample identifier, location, sampler's name, time and date of sample collection, and analyses requested using a black indelible marking pen All samples collected will be recorded on a Sample Management/Chain-of-Custody ` form which will track the sample from time of collection to delivery at the analytical laboratory All information recorded on the Sample Management/Chain-of-Custody form will be entered in ink r Before and after each subsequent soil sampling event, all sampling equipment will be cleaned Cleaning will consist of removing solid material from the sampling equipment using clear water and plastic bristle brush, washing the sampling equipment in a mixture of clear water and Liqui-Nox or Alconox (the use of phosphate based detergents will not be Y2Wd 10(wl 5) AMERICAN
