The rush to ethanol could harm water supplies in parts of the US, according to a report in Planet Ark today. The Ark says:
The US ethanol rush could drain drinking water supplies in parts of the country because corn — a key source of the country’s alternative fuel — requires vast quantities of water for irrigation, the National Research Council reported on Wednesday
…the use of more corn to make ethanol could drain water supplies like the Ogallala, or High Plains, aquifer, which extends from west Texas up into South Dakota and Wyoming.
Ethanol from corn is not the solution, even if it is good for farmers and farming companies in the midwest
