<br /> B,T,E,X=benzene,toluene,ethyl benzene,and xylene ND=none detected at or above laboratory reported detection limit
<br /> TPH-G=total petroleum hydrocarbons,quantified as gasoline ND X=none detected to a level of X
<br /> MTBE=methyl tertiary butyl ether *=detection limit raised due to elevated petroleum hydrocarbon result
<br /> NA=not tested for this analyte
<br /> [x]-EPA Method 602 analysis indicates a concentration of x,result is not confirmed by EPA Method 8260,however Future analysts by EPA
<br /> Method 8260 may indicate that MTBE is not present
<br /> V=other oxygenates/additives were analyzed by EPA Method 8260 and were not detected at or above the laboratory reported detection limits
<br /> ♦ =as of the fourth quarter 1999,MTBE was analyzed by EPA Method 602 and groundwater monitoring for gasoline oxygenates/additives other
<br /> than MTBE was discontinued
