<br /> "? Two soil samples were collected from soil boring SB--2; one from a
<br /> depth of five feet (SB2-51 ) and one from a depth of nine feet (SB2-
<br /> 9' ) . Sample SB2-5' did not contain detectable concentrations of
<br /> TPHg, TPHd, BTEX, Oil and Grease, or Purgeable Halocarbons.
<br /> Cadmium, Chromium, Lead, Nickel, and Zinc were present at levels
<br /> below their respective TTLCs and below ten times their respective
<br /> STLCs. Chromium was detected at a concentration of 3.B0 ppm, Lead
<br /> at a concentration of 8.79 ppm, Nickel at a concentration of 4.46
<br /> ppm, and Zinc at a concentration of 7.13 ppm, Cadmium was not
<br /> detected in sample SB2-51 . TPHg and TPHd were detected in sample
<br /> SB2--9' at concentrations of 220 ppm and 6.0 ppm, respectively.
<br /> Beii?ene was detected at a concentration of 150 ppb, Toluene at a
<br /> c=--: ntration of 620 ppb, Ethylbenzene at a concentration of 2400
<br /> ppb, and Xylenes at a concentration of 1400 ppb. oil and Grease
<br /> was detected at a concentration of 34 ppm in sample SB2-91 .
<br /> Purgeable Halocarbons were not detected. Cadmium, Chromium, Lead,
<br /> Nickel, and Zinc were present at levels below their respective
<br /> TTLCs and below ten times their respective STLCs. Cadmium was
<br /> detected at a concentration of 0.174 ppm, Chromium at a
<br /> concentration of 2.85 ppm, Lead at a concentration of 7.75 ppm,
<br /> Nickel at a concentration of 3.32 ppm, and Zinc at a concentration
<br /> of 5.90 ppm.
<br /> Soil samples SB3-51 and SB3=9' were collected from soil boring SB-3
<br /> from, depths. of.five feet and nine..feet,.: respectively. TPHg, TPHd',
<br /> BTEX, „Oi1 :and Grease, and 'Purgeable Halocarbons were- not detected:'
<br /> v in ;either :of othe .soil samples:- Cadmium, Chromium, Lead, Nickel,
<br /> `and Zinc were present at levels below their respective TTLCs and
<br /> below ten times their respective STLCs in both samples. In sample
<br /> ML
<br /> SB3-5' , Chromium was detected at a concentration of 3.44 ppm, Lead
<br /> at a concentration of 8.24 ppm, Nickel at a concentration of 4.10
<br /> ppm, and Zinc at a concentration of 7.99 ppm, In sample SB3-91,
<br /> Chromium was detected at a concentration of 3.40, Lead at a
<br /> concentration of 7. 17 ppm, Nickel at a concentration of 3.81 ppm,
<br /> and Zinc at a concentration of 6.79 ppm. Cadmium was not detected
<br /> in either sample.
<br /> Two soil samples were collected from soil boring SB-4; one from a
<br /> depth of five feet (SB4-5') and one from a depth of nine feet (SB4-
<br /> 9' ) . Soil sample SB4-5' did not contain detectable concentratiora4:
<br /> of TPHg, TPHd, BTEX, Oil and Grease, or Purgeable Halocarbons,
<br /> Cadmium, Chromium, Lead, Nickel, and Zinc were present at levels
<br /> below their respective TTLCs and below ten times their respective
<br /> STLCs. Cadmium was detected at a concentration of 0.314 ppm,
<br /> Chromium at a concentration of 4.02 ppm, Lead at a concentration of
<br /> 7.38 ppm, Nickel at a concentration of 4.57 ppm, and Zinc at a
<br /> concentration of 8.24 ppm.
