Detectable concentrations of volatile organic compounds {Ethylbenzene <br /> and Trichloroethane - TCE} were found in soil samples collected from three of the four hand <br /> auger borings. The concentration of TCE found in these samples ranged from ND up to 5.9 <br /> mg/kg. SOAC11\ <br /> WW Remedial Work T CC ­�)Vg <br /> On November 29, 1995 WHF consultants continued the investigation by digging an <br /> exploratory trench to a depth of 19 feet. A portable photo-Ionization detector was used to <br /> screen soil contained in the backhoe bucket.
