EII�t. <br /> Based on this evaluation it is recommended e ded that monitoring cease for the following wells with no <br /> constituent concentrations above screening levels for the groundwater-to-indoor air pathway <br /> MW-5 MW-15 MW-22S MW-28 <br /> MW-7 MW-17 MW-22D MW-29 <br /> MW-9 MW-18 MW-23S MW-30 <br /> MW-10 MW-19S MW-23D MW-31 <br /> MW-10A MW-19D MW-25S MW-32 <br /> MW-13 MW-21 S MW-27 AS-26 <br /> MW-14A MW-21 D <br /> Based on this evaluation, it is recommended that monitoring cease for the following constituents with <br /> no concentrations above screening levels for the groundwater-to-indoor air pathway <br /> • n-Butylbenzene <br /> • sec-Butylbenzene <br /> • 1,2-Dichloroethane <br /> a Ethylbenzene <br /> • Isopropylbenzene (cumene) <br /> Ile • Methyl-tertiary butyl ether(MTBE) <br /> n-Butylbenzene <br /> Toluene <br /> 0 1,3,5-Tnmethylbenzene <br /> Xylenes <br /> I <br /> For the remaining wells, it is recommended that the specific constituents showing concentrations <br /> above the screening levels be monitored until the concentration has been below the screening level for <br /> four consecutive monitoring events, as follows <br />! . MW-1 TPHg, Benzene <br /> • MW-2 TPHg, Benzene, Naphthalene, 1,2,4-Tnmethylbenzene <br /> • MW-3 TPHg, Benzene, Naphthalene <br /> • MVV-4 T Prig, Benzene <br /> • MW-6 TPHg, Benzene <br /> • MW-8D TPHg, Benzene <br /> • MW-9R TPHg <br /> O MW-11 TPHg, Benzene, Naphthalene (Naphthalene exceeded the screening level in July <br /> 1 2004 and was below for the following three monitoring events) <br /> IJ%Projec#AM94015MB-2931WoMng%ReportsILetter 3 July 2405 <br /> Requesting Reduction in SamplinglVapor Intrusion <br /> Pathway Evaluation-Letter doe <br />
