r <br /> r <br /> carefully poured into new, clean glass vials, sealed, labeled, <br /> and preserved pending transporting to the laboratory for <br /> ' analysis. The used bailer was discarded after use, and a new one <br /> was prepared for the next samples. Two vials were collected from <br /> each boring. Details of the sampling are given below. <br /> ' AUGER HOLE B-1: Upon retrieving, the bailer was almost full of <br /> water, the top 2/3rds of which was clear_ No odor or evidence of <br /> ' free product was noted. <br /> AUGER HOLE A-3: A new bailer was used; when retrieved at con- <br /> tained about 24" of slightly discolored water which had a <br /> ' definite petroleum odor. No free product was noted, however. <br /> AUGER HOLE A-2: A new bailer was used, and when retrieved had <br /> about 24" of clean water an it. No odor or other signs of <br /> contamination were noted. <br /> AUGER HOLE 9-2: Using a new bailer , about 30" of clear water was <br /> rtrieved; there was no evidence of contamination. <br /> AUGER HOLE C-1 : Because there were no new bailers remaining, the <br /> one used for auger hold B--1 was thoroughly steam cleaned and <br /> rinsed with de-ionized purified water- to remove any possible <br /> contaminants. When at was retrieved from the hole, it contained <br /> ' about 24" of muddy water; no odors or visible evidence of <br /> contamination was rioted. <br /> Sampling work was finished at about 6: 00 PM; because of darkness, <br /> ' at was not possible to grout the auger holes. Del-Tech personel <br /> properly sealed the barangs the following day under the <br /> supervision of Mr. Inferna of the EHD. The preserved sail and <br /> ' water• samples were delivered to FGL Environmental under proper <br /> chain-of-custody for analysis. Refer to Exhibit L, which also <br /> includes copies of the laboratory analyses. <br /> ' SUMMARY OF LABORATORY RESULTS: <br /> As tabulated on Table IV, laboratory analysis of samples taken <br /> ' during the work conducted on Jan. 16, 1992 indicated some <br /> contamination was present an two of the borings. Soil samples <br /> obtained from Auger Hole A-3 contained measurable amounts of <br /> ' Toluene, Ethylbenzene, Xylene, & TPH-G. The water sample from <br /> that boring revealed the presence of Ethybenzene, Xylene, and <br /> TRH--G. The soil sample from Auger Hole B-2 showed that BTEX was <br /> ' below detection limits, but a very minor amount of TPH-G was <br /> revealed. All other samples were below detection limits for all <br /> measured substances. <br /> 10 <br /> r <br />
