Mr. Thorpe also reported that he had received permission from sample the remain, the EHD tr., re- ng swoil for toluelle only because that wasall that had been found previously. Two by PGL ?ahoratorsamples were taken y On 10/I7/1991 and the tested for toluene. These samples are located 3n Figure 1 as described by Mr, Thorpe. NO toluene was found in either sample. Labol-atory data andchain-of-custody forms are attached. E�postll•t to the sten and air for about four months apparently evaporated whatever toluene that had been left in the spoil . Only about 10 yards of spoil as a maximum remain on the site, and based on the recent tests , it al'•pears that: Ilatural remediation has occurred and that no furkhe_i• remediat:it�11 is necessary.
