Yes, he's done a few things to disappoint me, such as opening up protected waters to off shore drilling (after insisting it was a terrible idea in his campaign) http://www.nytimes.com/2010/03/31/science/earth/31energy.html
But on April 2nd, 2010, he did something that made me really proud, or... his administration did anyways.
The EPA has greatly increased their standards for water quality and proclaims that very few valley fill permits will pass under the new guidelines (regarding water conductivity)

Granted, this is one.... medium. step (we've been making small ones all along, and while this doesn't solve all our problems, its certainly) in the right direction. We still have huge strides to make, but alas, I am currently incredibly grateful for Lisa Jackson, and the EPA, for taking our neighbors water quality into account.
Thank you! to everyone and anyone that assisted in any fashion, to making this happen!
