<br /> Notes
<br /> TPHg denotes Total Petroleum Hydrocarbons as gasoline analyzed by EPA Method 5030/8015
<br /> MTBE denotes methyl tertiary butyl ether analyzed by EPA Method 8260
<br /> DIPE denotes di-isopropyl ether analyzed by EPA Method 8260
<br /> TAME denotes tertiary amyl methyl ether analyzed by EPA Method 8260
<br /> TBA denotes tertiary butyl ether analyzed by EPA Method 8260
<br /> ETBE denotes ethyl tertiary butyl ether analyzed by EPA Method 8260
<br /> DW denotes deep facility well on site
<br /> NS denotes not sampled
<br /> NA denotes not analyzed
<br /> 1 =sample analyzed for HVOCs by EPA Method 524 2 All other constituents reported below method detection limit
<br /> (')= Gas is primarily composed of Benzene
<br /> Samples were also analyzed for 12-dichloroethane and ethyl dibromide by EPA method 8260 but were
<br /> not detected above the method detection himit
<br /> (***)=Samples were analyzed by EPA Method 80218 only therefore MTBE results are spurious
<br /> ICC Effluent denotes the sample collected between the first and second carbon vessels filtering the facility's water
<br /> 2CC Effluent denotes the sample collected after both carbon vessels filtering the facility's water
