Arthur:
To quote from G.Fred Lee's Flawed Technology of Subtitle D Landfilling of Municipal Solid Waste, "...VOC's in landfill gas, such as the chlorinated solvents TCE, PCE and the tranformation product vinyl chloride...can cause large-scale pollution of groundwaters by hazardous chemicals.... Landfill gaseous emissions contain a variety of volatile hazardous chemicals that are a threat to cause cancer and other diseases in those living in or using areas near a landfill." P35. Not a lot of detail in this report, but some useful citations.
I also reviewed a report on H2S (poisonous gas hydrogen sulfide, caused by fermentation of drywall in C & D debris that is landfilled) in Dan's Picks #1, NCRA News, 4 months ago.
I'm sure there is lots more out there, and I think your hunches are largely correct.

"Any possible contaminants" would include hydrogen sulfide that is produced when sheetrock is included with yard debris in ADC.
Among other sources, check G. Fred Lee's recent report (reviewed in July NCRA News) and other work for information on contaminants in landfill gases. See www.gfredlee.com.

Machine manufacturers were unable to certify that gas destruction would take place according to air board standards. The landfill owner came up with an alternate plan to compress this landfill gas and burn it in waste collection and transfer vehicles as a fuel.
The thought came to me that if the gas were burned in vehicles, then would it be a mobile source rather than a stationary source and perhaps less subject to regulation or non-pollute standards; would the fuel preparation equipment machinery remove any possible contaminants?
I have no experience on this topic and would appreciate references to persons with experience on this issue or written, authoritative documents; thank you.
