A day in PA at a Coal Mine Drainage Remediation Site

I had a really grand time up in PA doing some field work and collecting samples at a coal mine drainage remediation site. The site has several active Mn remediation beds, comprised of dolomite/limestone lined trenches. A lot of microbial life here, with algal mats abounding in most of the beds. Since it was a day trip, we only had a couple hours available at the site, so we disbanded to be as efficient as possible. Won't say much more, because lots of data left to process, except to say it was really neat to see Mn remediation in action! Also, I'd forgotten how good Pringles and powdered mini doughnuts are on road trips...
