<br /> Explanations:
<br /> ug/L=Micrograms per liter.
<br /> TPHg=Total Petroleum Hydrocarbons calculated as gasoline,analyzed by EPA Method 8260B.
<br /> TPHd-Total Petroleum Hydrocarbons calculated as diesel,analyzed by EPA Method 8015.
<br /> MTBE=Methyl Cert-butyl ether,analyzed by EPA Method 82608.
<br /> BTEX=Benzene,toluene,ethylbenzene,and xylenes analyzed by EPA Method 8260B.
<br /> -=Not sampled/Not analyzed
<br /> OCDUPI=Duplicate Sample of AR/M W-14C
<br /> QCDUP2=Duplicate Sample of SPWC-1S
<br /> QCDUP3=Duplicate Sample of TS/MW-1C
<br /> OCEB=Equipment Blank
<br /> QCTB=Trip Blank
<br /> MRP= California Regional Water Quality Control Board-Central Valley Region's Monitoring and Reporting Program No.R5.20040823
<br /> =The reporting limit for TPHd Is increased due to Interference from gasoline-range hydrocarbons.
<br /> '=Hydrocarbons reported as TPHd do not exhibit a typical diesel chromatographic pattem.
