Bloom Property Page 2 <br /> Report Phase IIA Investigation <br /> Bloom (Turnpike) <br /> April 14, 1998 <br /> Sample Collection, Geology &Analysis <br /> Soil Sample Collection <br /> The geology was logged by a professional geologist under the supervision of a <br /> registered geologist. Soil samples were collected on five foot intervals for <br /> geological and possible analytical evaluation. Upon collection, all soil samples <br /> were sealed with aluminum foil, capped, labeled and placed in a cooler chilled to <br /> 4° Celsius for transport to the laboratory following Chain of Custody protocol. <br /> One soil sample from the capillary fringe was analyzed (see below for analysis <br /> and results). <br /> Geology <br /> The geology is described in the attached boring log. The site geology <br /> encountered in the boring consists mainly of fine grained sediments- <br /> predominantly clay. The groundwater sample was collected from the base of a <br /> clay unit in a fine grained sand. <br /> Water Sample Collection <br /> Upon reaching total depth, a groundwater sample was collected using the Geo- <br /> Probe. A groundwater sampling tool was attached to the end of the probe and <br /> driven into groundwater. The tool was then retracted to expose a length of <br /> stainless steel screen to groundwater. A groundwater sample was then collected <br /> through a clean dedicated Teflon tube. The tube was fitted with a check valve <br /> and oscillated to siphon groundwater to the surface. Two 40 ml VOA vials <br /> preserved with HCL were filled along with 1 liter of water in an unpreserved <br /> amber glass container. Disposable gloves were worn by the sampling technician <br /> while collecting all samples. Extreme care was exercised during the collection of <br /> each sample to prevent agitation of the water. Upon collection all samples were <br /> checked for head space bubbles, labeled, inserted into foam holders and placed in <br /> an ice chest cooled to 4°C for transport to the laboratory. <br /> Soil Sample Analysis <br /> Soil and water samples were shipped to Sherwood Labs (DHS #1400), of Hilmar, <br /> California, for analysis. One soil sample taken from the capillary fringe zone <br /> from the boring and one water sample were submitted for analysis as follows: <br /> • Total Petroleum Hydrocarbons as Gasoline (TPH-Gasoline) by EPA method <br /> 8015m, and <br /> • Total Extractable Petroleum Hydrocarbons as Diesel (TPH-Diesel) by EPA <br /> method 3540/8015(m)(soil)-3510/8015(m)(water). <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
