(5) Water content had different effects on contaminant removal
from the soil, for the soil with 0.4% ofNOMcontent, the increase
of water content could decrease the removal efficiency; for
the soil with 5.4% of NOM content, the results were different,
when soil water content less than 8%, the increase of water
content could accelerate the contaminants removal, but when
soil water content increased to 13%, it led to lower removal
efficiency.
