<br /> Ground water samples from wells MW-1, MW-2B, MW-3B, and "A" wells, MW4A through
<br /> S MW'9A, were collected from HUI '
<br />�IQ 1hPb
<br /> TPH-g was detected in all ground water samples except MW-9A at concentrations ranging from 270
<br /> micrograms per liter(µg/L) in well MW-8A, to 45,000 µg/L in well MW-1 (Figure 7)
<br /> BTEX compounds were detected in all samples except MW-9A,ranging from 135 µg/L(MW-7A)
<br /> to 31,0001µg/L(MW-1)`ofbenzene,2 6µg/L(MW-8A)to 45,000µg/L(MW-1)of toluene,4 7 µg/L

<br /> total xylenes "
<br /> The only detected fuel oxygenates were 1,2-DCA, MTBE and DIPE 1,2-DCA was detected in all
<br /> samples except MW-7A, MW-8A and MW-9A, at concentrations ranging from 20 µg/L(MW-3B)
<br /> to 2,400 µg/L (MW-1) MTBE was detected in the samples collected from MW-1, MW-3B and
<br />' MW-4A at concentrations of 10 µg/L, 400 µg/L and 4 0 µg/L, respectively' DIPE was detected in
<br /> samples MW-1, MW,2B and MW-4A at concentrations of 15 µg/L, 18 µg/L and 3 0 µg/L,
