ON THE COVER
The Citronelle Oil Field has been selected by the U.S. Department of Energy as the site for a pilot project to evaluate CO2-enhanced oil recovery and geologic carbon storage. The project has brought together a diverse group of collaborators, including Alabama and North Carolina universities, the Geological Survey of Alabama, Southern Company, and Denbury Resources, the owner and operator of the field. Pictured above is a core log of the injection target in the Lower Cretaceous Donovan Sand and project team members performing site reconnaissance. See related article by Esposito et al., beginning on p. 53.

ON THE COVER
Constructed wetland system (foreground) for treatment of flue gas desulfurization (FGD) blowdown at Progress Energy's coal-fired power plant near Asheville, North Carolina. The six and a quarter acres of flow equalization basins and wetland cells are treating just over one half million gallons per day before discharge into the French Broad River.

ON THE COVER
Clockwise from top: A mine portal (T and T #2 mine, Upper Freeport seam, West Virginia), which has a ca 800 gal/min discharge of acid (mine water being treated by a state regulatory agency). The green color is from injection at the portal of NaOH (sodium hydroxide) reacting with reduced iron in the discharge to form a ferrous sulfate complex. It lies within the study area.
