Well today I went to the station to get a couple cans of diesel fuel for the tractor, I use off road because its 60 cents a gallon cheaper, than over the road, but at still 3.89 same price and reg gas. Anyway when I got there , there was a pumper truck emptying the tank. I asked what he was doing and he said the fuel had been contaminated. Like with radioactive waste or what? He said he didn't know but that he was to empty the tank and haul it back to the depot. I asked what are they going to do with it? He said dispose of it. Now Im thinking to my self how do you dispose of diesel fuel? If it was water run it through water filters, if it was gasoline, run it through they system again and drive off the gas vapors, or just mix it what home heating fuel.... So what do they do with contaminated diesel fuel????
