Question about clean up and how long it takes oil to break down.

Back in the seventies,one of our neighbors changed his oil a few times a year. He would pour the old oil on the fence line and it would kill the grass. The grass always grew back,so something must have eaten the oil or broke it down enough that the grass always came back. I know this is just a few quarts of oil,but will the same thing happen out in the marsh,and if so,what would be a realistic time frame for things to start growing again. Do we have an example of other oil covered marsh that has made a come back,or is this the great experiment?

the problem is that the marsh hasn't been growing in the first place

Not sure if I understand what you are saying. The grass in the marsh was alive before the oil came in,right.

bacteria in the soil use the oil as a food source and in some cases can support growth in organic life
I have seen first hand case histories where fuel was spilled on the ground, a dispersant was used to suppress the vapors and remove the fuel from the surface. the site was washed with water into the grass and the grass came back stronger than ever
the same principles apply to the sea but there is so much oil that it will take quite some time for nature to recover, especially considering the dramatic oxygen demand the decomposing oil will create in the water column which will affect the sea life

I'm not an expert on physical clean up , but i am sure that most of the oil will be naturally degraded.
I worked on "methanogens" bacteria that eats oil and I can tell you it would take decades to completley get rid of that oil.
The problem is that oil deep in the marshlands and the Fumes underneath the surface , some 20 miles long by half miles thovl will eventually reach and deposit/ stick in shallow water
wherever there is oil, there will be no life form (plants animals etc..) excpet for some
kind of bacteria that is able to utilize hydroocarbons as a food source
Effects on fishing and wild life will be for decades IMO

The Texas Department of Transportation sprayed emulsion on slopes to foster vegetative establishment for years...

I've seen this done on the median\neutral ground between Lake Charles and Lafayette a few years back.
So you are saying that the black spray is a petroleum based product that has grass seed in it?
Is it recycled oil?
