This report contains a <br /> { summary of previous findings and the results of the current phase of field investiga- <br /> tions and chemical analyses. <br /> In general, this phase of wort: resulted in the identification of no significant levels of <br /> fuel in shallow soils at the site. No contamination of soils beneath the main fuel tank <br /> area was identified in this current effort. Yet water acquired from well MW 3 exhib- <br /> ited significant levels of benzene and other fuel constituents. It is our opinion from <br /> -- the data now available that these high Ieveis of fuel components may have migrated <br /> from some as yet unidentified off-site source. <br /> 1 If you have any questions regarding this report, please contact either of the under- <br /> signed at(707) 864-2020. <br /> EVery Truly Yours, <br /> BALBI&CH"G ASSO CL4 TZS <br /> Db A Richesin _ �19 <br /> Engineering Geologist <br /> C.E. 1055 <br /> / �l//II� ,r;tom+ ,r C e�4 . •\1 1.')I'!1,'Y �e� 11 <br /> Phi L.Ch'a:n .E. _ ;S� •} �; )j <br /> Pri ipal Engi er <br /> GE 204 �, !
