Caption: Advection from the fermentation of increased amounts of ethanol spilled into the soil could pose a danger to buildings and people, according to researchers at Rice University. Bacteria breaks liquid ethanol down into methane gas, which expands as it diffuses. The fuel also produces benzene, a toxic hydrocarbon, which can leach into homes.
