Question

18.4 mg/L of toluene is in a groundwater plume. Compute how much of the following would be necessary for full mineralization of the toluene if each reaction were the only reaction responsible for accepting the electrons from toluene. You may ignore biomass growth. Express the results as a concentration in the groundwater (mg/L):

a) O2 consumption in aerobic respiration, mg O2/L (4 points)
b) SO42- consumption in sulfate reduction to sulfides, mg S/L (4 points)
c) NO3- consumption by denitrification to N2, mg N/L (4 points)
d) Fe(OH)3 reduction to Fe2+, mg Fe/L (4 points)
e) CH4 generation in methanogenesis, mg CH4/L (4 points)

Answer 1

"full mineralization of toluene???"
