Diesel puddle

Stonewall · Dec 13, 2002

Guys.... It's been washed into porous ground and rocks. It ain't gonna wash back out. It's wet and absorbed in to porous ground and rocks you would need a weed torch the size of a garbage can to cook it out of there. AND consider the agrieved party - she won't be happy until it's nice and clean - you know? Clean sheets and all.

Actually, Simple Green will help wash the diesel the rest of the way through the porous ground and rocks if not wash it back out. Simple Green is just a detergent. Detergents break the surface tension of dirt, break it down into small particles and make it slippery so it rinses away. What you're trying to do is rinse the diesel down into the soil so it is dispersed and filtered away. That will happen naturally over time with rain and weather - you just need to give it a little help in that direction.

Here's how the Simple Green web site says the same thing in "salesman speak mumbo-jumbo":

"Micro-Particulate Fractionalization™ (MPF) is the process whereby Simple Green All Purpose Cleaner/Degreaser breaks down large globs of oil, grease and fat into increasingly smaller microscopic droplets called "micelles.""

You certainly could dig it up and haul it away and be done with it. One significant advantage to that approach is seat time!

Stonewall,

My handle is taken from the name my mother christened the kid's boat, not from my vocation, (which is mechanical engineer in case you're wondering.) I was on the VFD when in college.

I'd have used speedy dry or kitty litter before washing it down to absorb as much as possible. I think now your options are to move the gravel/dirt or wait it out. Not familiar with the simple green stuff. I do know there is something that is used to disperse fuel when spilled while refueling a boat. Not sure what it is.

Thanks all for the ideas... I will try to find some of that green stuff on way home. Thankfully, it is raining today and I think that will help keep moving it along a bit.

Sure was amazing the size "wet spot" that can eminate from a 3/16 size hole drip by drip!!

Actually, moving much of the rock/dirt isn't a good option as right UNDER this part of driveway, is the water supply to house, the electrical line to the well pump and the drainage line from the downspout to the woods.

Maybe I can get a good buy on toothbrushes and start scrubbing....rock by rock.../w3tcompact/icons/eyes.gif

Since it's diesel, it ain't as bad of a problem as you think.
Diesel can be completely eliminated from soil by adding a layer of wood chips, and tilling them in to "fluff" the soil, and then adding PIG SHUT to the mix and tilling it again. Then, cover the whole mess with a plastic sheet.
6 months from now all you'll have is RICH soil.
If you can't get Pig manure, high nitrate content chemicle fertilizer will work too.
For rocks, visit your friendly barber shop, and get all the hair you can. Stuf the hair loosley into used pantihose, and lay them on the oil. The oil will wick onto the hair. The hair can then be disposed of in a proper landfill, or run thru the washing machine and reused.

Thanks hazmat. Here all this time I was envisioning you driving your little blue tractor in a big blue suit

I know you're right about the fuel dispersment medium for marine spills. I seem to remember that there is also a product out there that is a common by-product of modern manufacturing or food processing that can be spread out on standing petro spills to break them down. Can't remember the names of either one right now - Friday the 13th I guess.

Richard,

I vote with the simple green or actually dawn. It takes grease out of your way, maybe it'll take diesel to. I like dish soap. It is safe, and a good cleaner. Simple green is good stuff to. Comes recommended for cleaning heat pump/refrigeration coils by a HVAC mechanic. Also very impressive to use on heat pump coils, when the heat pump kicks on. It suds up very nice. One thing I wouldn't do is talk about it. Not to anyone, tell wifey and the dogs not to talk about. Don't tell anyone on the internet about it. Oh yeah, nix that last recommendation. If the wrong folks here about it, you WILL be removing that soil. And disposing of as haz waste. $$$$

Uh....talk about WHAT?

Not long ago I remember reading a study of the clean-up from the Exxon Valdez spill.

The study compared three methods of cleanup (detergent, steam, and the addition of fertilizer) to doing nothing. The Steam cleaning and the addition of detergent to the soil along the shore had the most immediate effect. It looked better after the treatment, however there was still considerable oil soaked into the soil just below the surface out of sight. The addition of fertilizer had no immediate effect.

Medium term in the areas treated with detergent or steam cleaned the oil remained just below the surface longer than the untreated areas.

Long term (10 years) almost all areas the bacteria returned and eaten the oil below the surface.

The theory was that the steam sterilized the soil killing the soil bacteria and forcing the bacterial population to rebuild from nothing in order to eat the subsurface oil.

According to the theory the detergent killed much of the soil bacteria and slowed the growth of the rest by helping leach nutrients from the soil.

Medium term the untreated areas were surprisingly better than the steam or detergent treated areas and second only to the fertilizer treated area.

The areas treated with a nitrogen-phosphate fertilizer had the best medium term results, with most of the ground free of visible oil. With the addition of the fertilizer the soil bacteria ate the oil fairly well.

I guess this means that if you dont want to dig out the diesel soaked dirt, you have a choice between the best short term result (with a detergent) or the best medium term result (by applying fertilizer).

Unfortunately I don't have a citation for the study but a web search for "exxon valdez bioremediation" and "oil spill bioremediation" turn up many hits.

(I guess the bright side is that it wasn't a spill of used motor oil. Diesel is clean compared to all the combustion byproducts and heavy metals in used motor oil.)
