07 April 1999 <br /> • AGE-NC Project No 98-0540 <br /> Page 3 of 9 <br /> Health Services (DHS)- certified laboratory and analyzed for <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> IMethod 5030f8015M, <br /> • Volatile aromatics(benzene,toluene,ethyl benzene and xylene BTEX)with methyl tertiary- <br /> butyl ether(MTBE) in accordance with EPA Method 8020, and <br /> • Fuel oxygenates,including tertiary butanol(TBA),di-isopropyl ether(DIPS),ethyl tert-butyl <br /> ether (ETBE) and tert-amyl methyl ether (TAME) and MTBE in accordance with EPA <br /> Method 8260M <br /> Grab groundwater samples were collected from all borings Samples were collected utilizing a <br /> disposable polyethylene bailer Upon retrieval, each sample was transferred into EPA-approved 40- <br /> ml VOA vials, containing 0 5 ml 18%hydrochloric acid as a sample preservative Care was taken <br /> to ensure that visible air bubbles were not present in the VOAs after filling and capping Ground <br /> water sample containers were labeled with the boring designation, date,time, and sampler's initials <br /> . Water samples were logged on a chain-of-custody, transported to a DHS- certified laboratory and <br /> analyzed for <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 5030/8015M, <br /> IVolatile aromatics (benzene,toluene,ethyl benzene and xylene BTEX)with methyl tertiary- <br /> butyl ether (MTBE) in accordance with EPA method 8020 <br /> 3 3 2 Logging <br /> During drilling activities, sample duplicates were monitored for the presence of organic vapor(OV <br /> ) <br /> using an organic vapor meter equipped with a photo-ionization detector (PID Thermo <br /> IEnvironmental 580A, 10 0 eV, calibrated to isobutylene) and were described on boring logs to <br /> accordance with the Unified Soil Classification System (USCS) Boring logs are included as <br /> Appendix A <br /> 3 3 3 Monitoring Well Installation <br /> . Soil borings B I(MW-1), B3(MW-2), and B5(MW-3) were completed as ground water monitoring <br /> Advanced GeoEniironmental,Inc <br />
