Work Plan—Soil Boring Installation Page 4 <br /> Russell Property <br /> Project 191.2 <br /> December 13,2000 <br /> removing a retaining bolt from the top of the device by inserting rods through the hollow <br /> stem of the probe rods. Removing this retaining bolt allows the drive point to retract through <br /> the sampling tube and a sample to be collected. <br /> 2.1.2 Geology <br /> A detailed log will be made of each boring. The information to be noted include such data as <br /> sample depths, soil / sediment type and description (color, texture, composition, hardness, <br /> moisture content, and post-depositional changes that have occurred in the sediments), and <br /> horizons of detectable contamination(detected by field methods). <br /> 2.1.3 Soil Sampling and Analyses <br /> The soil sample collection procedure will be as follows. The end of each stainless steel tube <br /> removed from the drive sampler and possibly submitted for laboratory analysis will be sealed <br /> with Teflon squares, capped with plastic end caps, secured with duct tape, labeled and placed <br /> in a cooler at 4° Celsius for transport to the laboratory using Chain of Custody protocol. <br /> Chain of Custody (CofQ forms are documents used to track the handling of samples. All <br /> dates, times, persons and companies handling the samples will be listed from the time the <br /> sample is collected to its ultimate disposal. All soil sampling equipment will be <br /> decontaminated between uses by washing using a steam cleaner. Nitrile gloves will be worn <br /> during sample collection and changed between the collection of each sample. <br /> All sampling equipment will be thoroughly steam cleaned before and between uses. Drilling <br /> steam clean water will be containerized in appropriate DOT containers for later recycling by a <br /> licensed hazardous waste hauler. No soil cuttings will be generated during the Geo-Probe <br /> drilling process. <br /> It is anticipated that three soil samples will be collected from each boring as described above. <br /> All of these samples will be submitted for analysis for diesel oil by EPA method <br /> 3540/8015(m) Total Extractable Petroleum Hydrocarbons(TEPH). <br /> The detection limit for this analysis is as follows: <br /> Table: Detection Limits-Soil <br /> Compound TEPH <br /> Detection Limit 5.0 <br /> Units I mg/kg <br /> 2937 Veneman Avenue,Suite B240 Geo-Phase Environmental Inc.
