<br /> r B T,E,X=benzene toluene ethyl benzene,and xylene ND=none detected at or above laboratory reported detection limit
<br /> TP11-G=-total petroleum hydrocarbons,quantified as gasolene ND X=none detected to a level of X
<br /> MTBE-methyl tertiary butyl olter *=detection lima raised due to elevated petroleum hydrocarbon result
<br /> NA=not tested for this analyte
<br /> r [x]=EPA Method 602 analysis indicates a concentration of x,result is not confirmed by EPA Method 8260,however Future analysis 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, groundwater monitoring for gasoline oxygenates/additives other
<br /> r than MTBE was discontinued
<br /> X=as of the third quarter 2000,MTBE and BTEX were analyzed by EPA Method 8021B
