<br /> ND=none detected at or above laboratory reported detection limit B,T,E,X=benzene,toluene,ethyl benzene,and xylene
<br /> ND X=nane detected to a level of X. TPH-G=totei pednleutn hydrocarbons,quantified as gas
<br /> =detection limit raised due to elevated petroleum hydrocarbon result. MTBE-methyl tertiary butyl ether
<br /> NA=not tested for this analyte
<br /> [x]=EPA Method 602 analysis indicates a concentration ofx;result is not confirmed by EPA Method 8260,however.
<br /> Future analysis by EPA 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 Lite laboratory reported detection limits.
<br /> *=as of the fourth quarter 1999,MTSE was analyzed by EPA Method 602; groundwater monitoring for gasoline oxygenatestadditives
<br /> other than MTBE was discontinued.
<br /> I=as of the third quarter 2000,MTBE and BTEX are analyzed by EPA Method 8021 B
