GW bioremediation
GW ex-situ Pump-and-Treat
Benzene
Toluene
Ethylbenzene
Xylene
BTEX water soluble monoaromatic compounds are the most toxic
BTEX decrease is used as evidence of remediation
Pump-and-Treat is quantifiable method

GW ex-situ Biofiltration
BTEX decrease is used as evidence of quantifiable bioremediation
Biofiltration stage 2 is a quantifiable method that allows close monitoring
Biofiltration with bioactivated biochar is excellent for BTEX removal
Biochar for carbon sequestration
