- " <br /> u <br /> 'I lv uam J. Munter&Associates <br /> On December 16, 1969, Jim Thorpe Oil , Inc. removed two (2) 1,000 <br /> underground fuel tanks which had contained leaded & unleaded <br /> gasoline and diesel; see Exhibit "A. " Five sail samples were <br /> taken as shown an Exhibit "B; " one at each end of Moth tanks, and <br /> one beneath the pump island. Results of lab analysis showed that <br /> the samples from the north end of the tanks, (GS#1 & GS#2,) were <br /> below detection limits, but contamination was reported for the <br /> other 3; (refer to Table I. ) <br /> i <br /> A Re-excavationfResample Work Plan was submitted by Jim Thorpe <br /> Oil, Inc. on April 4, 1990, to remove additional spoil and <br /> resample as shown on Exhibits "C" & <br /> Work commenced an August 17 1990, using Jim Thorpe Oil equipment <br /> - under the direction and supervision of W.J. Hunter, Registered <br /> Geologist, and Harlen Knoll, EHS. The sediments consisted <br /> primarily of very fine to fine, friable, sandy loam, tan to buff, <br /> with occasional lenses of grayish-tan clay. No distinct betiding <br /> was noted; soil wAs loose and poorly indurated. The sands were <br /> f primarily quartz and feldspar, with a clayey matrix. Portions of <br /> the excavation were damp, but quickly dried upon exposure to the <br /> air. <br /> } A definite petroleum odor was noted from the upper portion of the <br /> excavation, but became fainter with depth. Some discoloration <br /> was evident, especially in the area beneath the site of the pump <br /> i island. No free product, odor or color was noted in any of the <br /> { samples placed in water, although some showed a slight film on <br /> ( the water surface. <br /> The hole was extended to about 25' X 25', and deepened to <br /> { approximately 20' at the south end and about 23--24' at the north <br /> end. Although there was still some apparent contamination <br /> remaining, the limitations of the equipment prevented further <br /> excavation. Six C6) samples were taken from the sides and bottom <br /> a of the excavation an indicated an Exhibits "E" & "F." They were <br /> properly sealed, labeled, and placed an ice by W. J. Hunter, <br /> stared overnight in a freezer, and transported to Canonie lab the <br /> following day under proper chain of custody. <br /> Analysis of the laboratory __ results --showed that the sidewall <br /> samples taken an the south, west, and north wails, and the west <br /> bottom . sample, (B-1,) were clean. However,. the east bottom <br /> sample, (B -21) and the sidewall sample from the east wail (SW-4,) <br /> still contained detectable levels of contaminants. Refer to <br /> Exhibit "E" and Table II. for test results. <br /> j <br /> e <br /> `J PROPOSED WORK TO ENLARGE EXISTING EXCAVATION TO THE SOUTH AND <br /> EAST, RESAMPLE AND RETEST FOR CONTAMINATION: <br /> 2 <br />
