1 <br /> The hole was filled in with the removed spoil' to avoid passible in3ury to humans or animals. A visit to the site on September 11 <br /> revealed no evidence of surface contamination or odors. <br /> INVESTIGATIVE WORK DONE UNDER WORKPLAN DATED OCT. 31 1991: <br /> ' On October 3, 1991 , Wm. J. Hunter & Associates, <br /> a workplan to the EHD (WJH* ) submitted <br /> ' deep holes <br /> concentrically around proposing <br /> the QSsite tofhathe auremover ediDUST. (That <br /> ' workplan is included as Exhibit G. ) Work began on November 6 <br /> 1991 , using Jim Thorpe Oil equipment under the supervision of <br /> William Hunter, RG, The first boring was located 12' westerly <br /> ' from the UST site, and encountered contaminated soil at 4 '6". <br /> Augering stopped at 4'911 , still in contaminated soil . No water <br /> was noted, and no soil sample was taken. Refer to Plot 1E and <br /> ' cross-section A-B, (Plate XI , ) for details. <br /> Because of the shallow depth of the contamination, it was decided <br /> ' to use the backhoe bucket where possible instead of hand <br /> augering. A spot was measured 24 ' west 0f auger-hole #1 , and a <br /> narrow trench was dug to 7' ; contamination was noted below 6' . A <br /> 5011 sample was taken at 7 ' using the backhoe bucket. The trench <br /> was refilled with the removed spoil . Refer to Plot 1A and cross- <br /> section A-B for details of the lithology. <br /> ' The backhoe then moved to a location 24 ' south of the former UST <br /> site, and a trench was dug to 6 ' , where contamination was <br /> observed. The soil from the bottom was moist, but no free water <br /> ' was noted. No sample was taken, and the trench was refilled with <br /> the removed spoil ; refer to Plot 1B and cross-section C-D for <br /> details. <br /> ' The backhoe was moved an additional 9' farther south - .33 ' from <br /> the UST site - and a trench was dug to 7' . A strong petroleum <br /> odor was noted below 6'6" in sandy clay. A soil sample was taken <br /> ' from bottom using the backhoe bucket and the trench was refilled. <br /> Lithology encountered 1s shown on plot 1C and cross-section C-D. <br /> ' A location was selected 30' east of the UST site, and the backhoe <br /> dug a trench to 7 '; a strong petroleum odor and visible free <br /> product was noted below 6 '6". A soil sample was taken at 7 ' , and <br /> the trench was refilled with removed spoil . Refer to Plot ID and <br /> ' cross--section A-B for details of the lithology encountered. <br /> Using the hand auger, 3 borings were made north of the former <br /> ' tank site: they are labeled #2, #3, and #4 on Plate VII; <br /> lithologies encountered are shown on cross-section C-D and Plots <br /> 1F, 18, & 1H. Contamination was noted in all three auger holes, <br /> 3 <br />
