Can you tell me anything about bio-environmental engineering?

I have been looking at jobs in the Air Force and after taking the ASVAB it shows that I qualify for bio-environmental engineering.

I was wondering if anyone knows anything about it, maybe what I will be doing exactly, or possibly own personal experiences.

I have done some research and google searching on it, and I plan to make it my first choice as it has stuck out to me since I first looked at the job list.

This is what I have read on it.

Also could you recommend to any jobs in the Air Force or heads up possibly?

Thank you.
