We are also planning to conduct additional investigations to further <br /> delineate the extent of the contamination,which it appears may have gone beyond the boundaries of the site. This <br /> will require that we obtain the approval of nearby property owners to enter their properties. We have already <br /> discussed with you, the problems we are having in this matter and wish to implement an interim measure to <br /> remove some of the contamination from monitoring well MW-5(Figure 1)during this period as described below. <br /> During the quarterly sampling process, several gallons of water are removed from all the monitoring wells and <br /> stored in 55-gallon steel drums. We then have a vacuum truck come to the site and pump the water out of the <br /> drums. At the time of this water removal,we propose to have the vacuum truck insert a clean section of PVC <br /> tubing which is attached to the vacuum hose into well MW-5 and pump the groundwater out of the well for a time <br /> period of approximately 2 hours. <br /> Groundwater samples will be collected before pumping begins and after the pumping is finished,and analyzed for <br /> total petroleum hydrocarbons as gasoline(TPHG)and benzene,toluene,ethyl benzene and total xylenes(BTEX). <br /> The water will be collected and transported by a properly licensed waste hauler and recycled at a local refinery. <br /> Results of the TPHG/BTEX analysis and copies of the transport manifest will be provided in our quarterly <br /> groundwater monitoring reports. The next groundwater sampling will be conducted during the second or third <br /> week of December 1991 and the drums and monitoring well MW-5 are scheduled to be pumped out during the <br /> first or second week of January 1992. <br /> If you have any questions regarding this matter,please call. <br /> Sincerely, <br /> RESNA Industries,Inc. <br /> 1. <br /> Richard Garlow, R.E.A. 1365 <br /> Senior Project Geologist <br /> RG/sw <br /> ow Jim Rubin,RESNA Industries, Inc. <br /> Jack Griffith,Quik Stop Markets <br />
