<br /> 3 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLES
<br /> f During the September 2003 sampling event, groundwater samples from 31 monitoring points were
<br />' collected from HU-1 through HU-5 and submitted for laboratory analysis for the constituents listed
<br /> in Section 2 2 Analytical laboratory results are summarized in Tables 2-5
<br /> , HU-1 ,
<br /> Ground water samples from wells MW-1, MW-2B, MW-3B, and "A" wells, MW-4A through
<br /> MW-9A,were collected from HUI

<br />' TPH-g was detected in all ground water samples except MW-9A at concentrations ranging from 140
<br /> micrograms per liter (µg/L) in well MW-6A to 120,000 µg/L in well MW-1 (Figure 7)
<br /> BTEX compounds were detected in all samples except MW-9A, ranging from,31 µg/L (MW-7A)
<br /> to 25 000MW-1 benzene, 2 7 L MW-8A to 35,000 µg/L (MW-1) toluene, 7 0 gg/L

<br />' The only detected fuel oxygenates were 1,2-DCA and DIPE 1,2-DCA was detected in samples from
<br /> MW-1, MW-2B, MW-4A, MW-5A and MW-6A, with concentrations ranging from 17 µg/L
<br /> (MW-6A) to 4,600 µg/L (MW-4A) DIPE was detected in samples from MW-1, MW-2B and
