02 November 2001 ; <br /> AGE-NC Project No.,98-0440' <br />' Page 3 of - <br /> 3.2 "ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> TPH-g was detected in the:water-samples collected from monitoring wells MW5 and' MW6 at , <br /> " ,concentrations of 180 micrograms per liter {µg/1) and 100 µg/1,' respectively. TPH-d was not ' <br /> ,detected at or above laboratory reporting limits in.the water samples. . <br /> One or more BTEX compounds-Were detected in the water samples collected from wells MW5 and <br /> MW6,at concentrations as high as 11 µg/l benzene,0.54 µg/1 toluene,29 µg/i ethylbenzene and 6.6 , <br /> gg/l <br /> .6 - <br /> µg/1 total xylenes. MTBE was.not,detected'at or above laboratory reporting limits in the ground <br />' water samples: - <br /> Norie.of the analytes were,d'etected at or'above laboratory reporting limits in the water sample .. <br /> •. . .collected from domestic.well DW5157. <br /> 'Current and previous analytical.results are summarized'on Table 2.

Dissolved' hydrocarbons were' <br /> encountered in the down-gradient direction from the former`•USTs in samples' •from <br /> monitoring wells MW5 and MW6: Dissolved hydrocarbons decreased to non-detectable <br /> I; concentrations in well MW2.,Dissolved hydrocarbon concentrations remained non-detectable' <br /> samp <br /> -wles from wells MW 1,:MW3 and MW4,and concentrations increased in samples from <br /> ells A <br /> MW5 and MW6. map showing the approximate extent of dissolved-TPH-g is <br /> L presented in figure 5: , <br /> ` • ,' The lateral extent of petroleum hydrocarbon-impacted'ground-water has not,been defined: , <br /> toward theorth and no <br /> n � MW5,andMWb."The hydrocarbon-plume is'fairly <br /> rtheast beyond <br /> " well defined'to the south,,east, west and northwest. <br /> Advanced GeoEnvironmental,Inc. <br />
