<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 petroietan 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 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 oxygenates/additives were analyzed by EPA Method 8260 and were not detected at or above the laboratory reported detection lktnits.
<br /> ♦=as of the fourth quarter 1999,MTBE was analyzed by EPA Method 602; groundwater monitoring for gasoline
<br /> oxygenates/additives other than MTBE was discontinued.
<br /> P-as of the third quarter 2000,MTBE and 13TEX were analyzed by EPA Method 802113
