IL <br /> 12 June 1998 <br /> AGE-NC Project No. 98-4398. <br /> Page 3 of 7 <br /> 31. SCOPE OF WORD <br /> The,scope of work for this preliminar''s to assessment included"advancement of three soil probe <br /> L borings, collection of soil and ground water samples for analysis and description, and preparation <br /> of a preliminary:assessment report. <br /> 3.2. SOIL <br /> . PROSE BORINGS <br /> Advancement of soil the probe borings was accomplished.utlizing a van-z�rtounted Geoprobe 5400 <br /> L <br /> equipped with 1 i25=inch diameter probe rods with an attached 23 5-itichdiameter soil sampler, <br /> using"direct push"technology. Probe boring P1 wasadvanced neafthe former UST area;probe <br /> borings P2,and P3 were advanced-'-'orth of the former UST area. Soil probe boring locations are,- <br /> depicted on Figure 2. <br /> 3.3 SOIL SAMPLE COLLECTION <br /> Discrete soil samples were continuously" Pi utilicored fromzang:.a Geoptabs'Ma' cro- <br /> -core sampler <br /> with 48-inch acetate sleeves.One,discrete soil sample was collected from P2 at T 1 Ys=feet bsg using <br /> a Geoprobe soil sampling assembly loaded with pre-cleahed"1 125-inch by 6-inch brass`sleeves.No <br /> . soil samples were collected from P3 Selected soil-sang les were reserve <br /> t p p d by covering both ends <br /> of the selected sleeve section with Teflon,sheets,capping,and sealing with tape.Each sample sleeve <br /> was;labeled with soil probe boring designation,depth,time,date and.sampler's initials. <br /> The samples were stored in:a chilled container and transported,under a chain-of-custodyto a state- <br /> certified <br /> tatecertif ed Iaboratory. Selected samples were analyzed in accordance with:` <br /> • EPA Method 5030/8015M for total petroleum hydrocarbons quantified asgasoline(TP1 -$), <br /> • EPA Method 8020 for BTE&X and methyl tertiary butyl ether(MTBE),and <br /> • EPA Method 8260 for oxygenated compounds including tertiarybutyl.ether(TBA),methyl - <br /> ,, tertiary butyl ether(MTBE),di-isopropyl ether(DTPE),ethyl tertiary butyl ether(ETBE)and <br /> tertiary amyl tt ethyl ether(TAME). <br /> 3.4., GROUND WATER SAMPLE COLLECTION <br /> L <br /> One grab ground water sample was successfully collected from P 1 utilizing hydro-punch technology; <br /> _ Aa)am&dGeoEovirgnmentil Isle. <br />
