TPPH was not detected in the groundwater <br /> sr sampIcs from wells MW-2,MW-4 and MW-6. Ae.-7ene was detected in the groundwater samples <br /> j from wells MW-6 and MW-7 at concentrations of 0.6 ppb and 5.6 ppb,respectively. Benzene was <br /> not detected in water samples collected from any other wells.
