<br /> [s]=EPA Method 602 analysis indicates a concentration of x;result is not coafumed by EPA Method 5260,however.
<br /> Future nnolysis 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 the laboratory reported detection limits.
<br /> ♦m as of the fourth quarter 1999,y1TBE was analyzed by EPA Method 602; groundwater monitoring for gasoline oxygenates/additives
<br /> other than MTBE was discontinued,
<br /> as of[he third quarter 2000,MTBE and BTEX are analyzed by EPA Method 8021 B
