1 . • <br /> 12 March 2000 <br /> AGE-NC Project No. 98-0432 <br /> Page 2 of 3 <br /> with four six-inch long brass sleeves.Upon removal from the sampler,the sample sleeve is separated <br /> with a clean soil knife. The exposed ends of the selected sleeve will be covered with Teflon sheets, <br /> capped and sealed with tape. Soil samples will be field screened for the presence of volatile organic <br /> compounds using an OVM. <br /> Following sample collection, each preserved sample sleeve will be labeled with the boring location, <br /> depth,time, date and sampler's initials. Appropriately sealed and labeled samples will be placed in <br /> a chilled container under ice and pending transportation to a Department of Health Services (DHS) <br /> certified laboratory. <br /> For the collection of grab ground water samples, soil probe borings will be advanced to the top of <br /> the ground water table as identified by collection of a saturated soil sample. Once ground water has <br /> been encountered,a Geoprobe push-driven water sampling device will be advanced two to three feet <br /> into the water bearing zone. Grab ground water samples will be collected using a Geoprobe water <br /> sampling assembly fitted with a pre-cleaned one-inch 0.01 slotted temporary well screen. Each <br /> ground water sample will be extracted by lowering a Teflon bailer through the hollow center of the <br /> push rods into the screen section. Samples will be collection in laboratory-supplied, 40-m1 volatile <br /> organic analysis (VOA)vials containing 0.5-m1 of hydrochloric acid as sample preservative and 1- <br /> liter amber bottles. The labeled vials and bottles will be placed in a chilled container under ice <br /> pending transportation to a DHS certified laboratory. <br /> LABORATORY ANALYSIS <br /> Selected soil and/or ground water samples will be submitted to a DHS-certified laboratory and <br /> analyzed for the following: <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified and <br /> • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) and methyl tertiary butyl ether <br /> (MTBE) by EPA Method 8020. <br /> DECONTAMINATION <br /> All sampling tools used for sample collection will be thoroughly rinsed with clean water after being <br /> washed with a solution of Alconox. All probing rods will be cleaned prior to advancement at each <br /> probe boring location. <br />
