<br /> ND-none detected at or above laboratory reported detection limit B,T,E,X=benzene,toluene,ethyl benzene,and xylene
<br /> ND X=none detected to a level of X, TPH-G-total petroleum hydrocarbons,quantified as gas
<br /> *=detection limit raised due to elevated petroleum hydrocarbon result. MTBE=methyi tertiary butyl ether
<br /> NA-not tested for this analyte
<br /> lxj=FPA Method 602 analysis indicates a concentration of x;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 oxygernates/additives were analyzed by EPA Method 9260 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
<br /> other than MTBE was discontinued.
<br /> I-as of the third quarter 2000,MTBE and BTEX are analyzed by EPA Method 8021B
