BTEX definition
Examples of BTEX in a sentence
Soil cleanup levels established for BTEX compounds and polynuclear aromatic compounds coincided with U.S. EPA Region IX PRGs for industrial/commercial land use (PRC, 1995c).
Soil and groundwater samples were collected and analyzed at an off-Site laboratory for TPH, BTEX compounds, and SVOCs. The primary chemicals of concern are TPHg, and BTEX compounds, although several SVOCs were detected at low concentrations, including naphthalene (maximum concentration of 6.4 mg/kg) and 2-methylnapthalene (maximum concentration of 5.5 mg/kg) (PRC, 1994e).
Maximum concentrations of TPHg and BTEX compounds detected in the NEX service station area were as follows: TPHg (1,500 mg/kg); benzene (75 mg/kg); toluene (220 mg/kg); ethylbenzene (340 mg/kg); and xylene (910 mg/kg).
BTEX compounds were also detected, but generally at low concentrations below I mg/kg (PRC, 1991b, 1994a).
Soil and groundwater samples, as well as a sample of sludge were collected when Sump 60 was removed in October 1990 and analyzed for VOCs (including BTEX), TPHg, TPHd, SVOCs, and metals.
