Is there enough space?
Will bioremediation be quick enough if ex-situ treatment is used?
Will it be too difficult to operate/maintain?
Will it cause too much disruption excavating and transporting the soil?
Will toxic contaminants be released when moving the soil?
Bio-Farming
Windrow Composting
Bio-Piling
Soil Screening
Bio-reactor
TRUE
FALSE
To ensure the area is sufficiently oxygenated.
To harvest the crops.
To collect the leachate.
To catch escaping volatile contaminants.
None of the above.
To prevent contaminant leaching from treatment.
To optimise/enhance bioremediation.
Sewage sludge from waste water.
Waste wood from the wood industry.
Manure/Fertilisers
Benzene from oil production sites.
Improved aeration.
More nutrients
Lower Permeability
A greater population of microorganisms.
I would expect to see all of the above.
Need impervious layer.
Must cover the area of land (i.e. make enclosed)
Must only treat small volumes at once.
Should try to make soil into a deep heap.
None of the above are true.
For better drainage and collection of leachates.
To direct escaping volatile gases for easier collection.
The pad is covered with HDPE to supply additional nutrients.
It ensures more uniform treatment.
You can treat a larger volume.
No monitoring is required.
Requires less space?
No microorganisms are required.
