Based <br /> on the concentrations of TPHg, BTEX, and fuel oxygenates detected in MW-8 and MW-9 <br /> during the initial sampling (April 9, 1999), collection of additional samples are warranted <br /> to confirm the previous results and to establish a trend in hydrocarbon concentrations. <br /> Given the concentrations detected in these two monitoring wells, we are also <br /> recommending that monitoring wells MW4 and MW-7 be sampled. We recommend that <br /> groundwater samples be analyzed for TPHg using USEPA 8015, BTEX using USEPA <br /> 8020, and fuel oxygenates using USEPA 8260. Once the analytical results have been <br /> received, further recommendations regarding assessment (if warranted) and groundwater <br /> sampling will be presented. <br />!I Sincerely, <br /> EMCON <br /> a J son, R.G 5 6 Mark CapjX. 6561 <br /> oje anager Project Geologist <br /> cc: Mr. Lawrence Beasley Date u et <br /> Post-its Fax Note 7671 � l5 . pages <br /> 1 To A_ , From <br /> Co./Dept n7VtV Co. r 5 <br /> " # /�A/ � _ Phone ) g . o <br /> Fa% N WA 610 (0 <br /> _ Fax <br /> l <br /> 9 <br />
