cleaned. Cleaning will be conducted on-site on all sampling equipment between each sample interval. Soil samples will be obtained using a direct -push rig and acetate liners. Each 4 -foot drill rod is lined with an acetate liner and driven into the soil. The rod and liner are removed and the liner is pulled out from the rod. A 6 -inch section of the liner will be cut and sealed with Teflon tape and plastic end caps, taped and labeled with the following information: data, time, project ID, sample ID, name of sampler and type of analysis. This sample will be immediately placed into a cooler containing dry ice or frozen chemical. The samples will be delivered to a state certified laboratory following under chain of custody protocol within the sample hold time. Soil in the liner will be described according to ASTM standard practice for description and identification of soils (ASTM D-2488-84). Stratigraphic, genetic and other data/interpretations will also be recorded. Soil properties may also be determined from the sampler shoe. These field observations will be noted on a log prepared for each boring/well. During sampling, latex gloves will be worn to prevent cross -contamination with other samples. The disposable gloves will be discarded after collecting samples from each liner. Soil samples will be collected at four foot intervals, at significant changes in lithology and intervals of obvious contamination in order to develop a complete profile of soil contamination. 10.0 SOIL VAPOR SAMPLING PROTOCOL A proposal will be submitted to the lead Regulatory Authority with proposed boring/sampling locations. The exact location and number of borings at each site will be determined in the field by the Project Geologist/Engineer. Prior to arriving at the sample site, the drill rig/augers will be steam cleaned and all sample equipment will be cleaned. Cleaning will be conducted on-site on all sampling equipment between each sample interval.
