r r <br /> were up in this particular area. At one time in the magnitude of 5000 parts <br /> per billion for TE. They have some sizable concentrations under-flowing <br /> .the pend. They were pretty strong in this finger. Whereas, this finger was <br /> much larger but much more dilute. They were looking levels in the <br /> hundreds of parts per billion, These ether lobes down In here are less than <br /> 100, <br /> Mr. Hill interjected that they were lees than 25 ports per billion. The T E <br /> one was extracting in the g's parts per billion. <br /> Mr. Carson continued by stating that there was a let of dilution going on <br /> as you are pulling the clean along with the contaminated water that why <br /> it was different from the monitoring well data, It would be higher. <br /> Ms, Warden asked if there wasn't an extraction well located at the TDE. <br /> Mr. Carson replied that it was at the end of Hoophole road, several years <br /> ago they did.sone pond water sampling just above the bottom of the pond <br /> in this particular area working with sediments. That was why the areas <br /> were painted gray. 'These were the areas that were previously defined by <br /> the Uses who did the work for there based on those finding that the <br /> upwelling was occurring In those particular areas, There was an awful lot <br /> associated with this now also with SD5 and measurable concentrations in <br /> the pond and they've seen that rarer. <br /> IVIS, Warden asked If they had seen a lot of MTBE in that particular area. <br /> Mr. Carson was unsure. <br /> Mr. Dill wasn't sure if they had seen any of the analysis. <br /> Mr. Harrington stated that that was all corning out the east side of the <br /> pond. <br /> Ir. Carson agreed and was going to talk about the residential well <br /> sampling program that was dome in this area,, Down in there where they <br /> have remaining homes. That was one of the constituents they have been <br /> seeing in the residential wells. It had been showing for a number of years, <br /> It was not a constituent of these plumes. It was something that was <br /> becoming more pervasive in the environment. <br /> Mr. Harrington felt that boat usage was helping the situation. <br /> Mr. Carson agreed and stated that it was showing up in other areas that <br /> were not near water bodies because it was an additive to gasoline as a <br /> 1 <br /> 4 <br />
