TPH-G, <br /> ethylbenzene, and total xylenes were detected only in the <br /> ground water samples from monitoring well AW-3 at <br /> concentrations ranging from 0. 3 to 210 ppb. <br /> Based on the above findings, we believe no further <br /> characterization of the dissolved-phase hydrocarbon plume is <br /> necessary at this time. <br /> If you have' any questions, Please feel free to call me at <br /> (818) -953-2626. <br /> Sincerely, <br /> s. re" <br /> Stephen Pao <br /> Field Engineer II <br /> enclosure <br /> Mr. Gordon L.
