• Fuel oxygenated compounds — di-isopropyl ether (DIPS), ethyl-t-butyl ether (ETRE), <br /> tert-amyl methyl ether(TAME), t-butanol (TBA) by EPA Method 8260 <br /> 1� <br /> 3.3 Floating Oil <br />' Floating oil has been removed from MW-2 periodically, starting in January 2000 A total of <br /> approximately 10 1 gallons of oil has been removed and the results are summarized in Table 3 <br />' 4.0 DiscussioN <br />' 4.1 MW-4 <br /> Groundwater from MW-4 shows continued contamination from TPH-gasoline, oxygenates and <br />' BETX It remains free from TPH-diesel and motor oil contamination, indicating that MW-4 has <br /> not been affected by contamination from the former diesel and used oil USTs The source of the <br />' gasoline contamination is unknown at this time <br /> I4.2 Waste Oil USTs <br /> Analysis of MW-2 sampled on 27 June 2001 shows no change in contamination from motor oils, <br /> TPH-gasoline and MTBE BETX and DIPE remain at low levels MW-1, MW-3 and MW-4 <br /> continue to remain free of motor oils contamination The former waste oil USTs continue to be <br /> an apparent source of groundwater contamination from a number of petroleum hydrocarbons <br /> This contamination appears to be confined to the area immediately adjacent to MW-2 <br /> 4.3 Diesel USTs <br /> MW-1 (site of the former diesel USTs) is now free of contamination from diesel The TPH- <br /> Idiesel contamination levels have decreased to zero, as shown in Figure 5 No other targeted <br /> contaminates are evident <br /> IMW-2, MW-3 and MW-4 are also free of diesel contamination, indicating that diesel no longer <br /> poses a threat to the environment at this site <br /> Enwroneering,Inc Project No 01-006 011 page 4 <br /> I <br />
