<br /> BACKGROUND
<br /> This project has progressed through fov.r phases
<br /> inatallation. WA collected soil es prior to monitoring well
<br /> s
<br /> cmples beneath three underground storage
<br /> tartka which were removed
<br /> from the site, and from six soil borings that were
<br /> drilled ground the perimeter of the tank excavations,
<br /> summarized below Phases 1, 2, and 3 are
<br /> and are detailed in our letter report of 3D October and
<br /> proposal of 25 November 1986,
<br /> In Phase I, conducted in Au&ist 1986, WA collected six soil samples for
<br /> w- chemical analysis from beneath an excavation that contained a 1,000-gallon
<br /> gasoline tank and an 8,000-gallon weed oil r g lion
<br /> _. Presented in Table 1. In Phase
<br /> tank. Results of the dualysis are
<br /> 11, conducted in September 1996, GTA drilled
<br /> six borings around the perf.meter of this
<br /> - extent of hydrocarbons tank excavation Co determine the
<br /> in the sof?. Four samples, ono from each
<br /> not boring, B-,t
<br /> through B-4, were Zollected and analyzed for
<br /> B-6 were TFand BTX, Borings B-5 and
<br /> a:� since in the laboratory since no odors were noted in the,
<br /> field. Analytic results for this
<br /> Phase are also presented in Table 1. Pharse
<br /> III of this project, performed
<br /> below the
<br /> in Detober 1986, iTIVOl.ved excavating 31 ft
<br /> located, ground surface where the
<br /> 1,000-gallon gasoline tank had been
<br /> collecting soil Samples and analyzing them to determine the vertical
<br /> extent of hydrocarbons under this tank. The 31-ft sample
<br /> 3,300 ppm TFHC. (BH31) contained
<br /> In December 1986, Phase IV was
<br /> Performed during the removal of a
<br /> formulated oil tank (F-Oil), Soil samples were collected in and
<br /> --- bottom p below the
<br /> Of the tank excavation. The two samples analyzed were below detection
<br /> for TT-VC and BTX- The results are presented in Table 1.
