Colorado School of Mines-Environmental Science and Engineering

It sounds like you don't have to be an engineer to get into this program.  The acceptance rate is very high, despite the fact that it is one of the top engineering schools in the country.  However, the price tag is very high--$33,000 for in-state alone--and remission of all of those fees is not guaranteed.  It sounds like an interesting program, so it may be worth checking out.
