When the pug mall hopper was full , it dumped into a truck waiting beneath it; the treated material was then placed on concrete in piles of approximately 14 CY 's each. On August 7, 1992, a total of 40 soil samples were taken; which were composited into five (5) for analysis. They were tested for kerosene, diesel , and oil , (TEPH, ) in order to monitor progress. The results, (Table IZ & Exhibit G, ) showed that the components diesel and oil were still present, but at considerably lower levels than measured prior to start of remediation. The approx- imate location of these 5 areas are indicated on Plate VII as CS #1 thru CS #5. Innoculativn time was 22 days, ending on August 15, 1992. Field monitoring for TPH was done during the period August 15 until November 20, when it appeared that contamination levels had dropped to acceptable limits. In order to establish final testing requirements , and to monitor remediation results, three (3) soil samples were taken on November 20, 1992; their approxi--- mate locations are shown as CS #1-CS #3 on Plate VIZ. The samples were tested using EPA 1311-Toxicity Characteristic • Leaching Procedure for Total Recoverable Petroleum Hydrocarbons using Standard Method 552OBF. The results revealed that tested sustances were below detection limits. Refer to Table III Exhibit H for details. On December 15, 1992, Jim Thorpe 011 , Inc. submitted a brief workplan to the County EHD, outlining sampling procedures and laboratory tests to be run. It was agreed that final sampling would consist of the following procedure: one (1 ) sample would be taken for each 200 CY 'ds of soil and tested for TPH-D; one (1 ) sample for each 200 CY 'ds & tested for BTEX s and one ( 1 ) sample for each :00 CY 'ds and tested for O&G, (5520B) and TPH, (5520F) . Refer to Exhzbzt I for a copy of that correspondence. Sampling was done on December 18, 1992 by hark /-hock of FGL Environmental Laboratories as directed by Harlen Knoll of the County EHD, and supervised by Richard Thorpe & Jam Kassinger. The locations and ID number of the samples are shown on Plate VII. The results of that analysis, (Table IV, ) revealed that BTEX , Oil & Grease, and TRH (5520F) were all below detection limits. TPH-D was detected an only five (5) samples, at levels ranging from 1 .0 to 3. 2 mg/kg. A complete list of the laboratory results and chain-of-custody sheets are included in Exhibit J. An analysis of allowable levels that can be left in place was • made using the LOFT Manual Table 2-1 , Leaching Potential Analysis 5
