Posted by Betsey Seibel on Mon, Aug 13, 2012 @ 04:26 PM

Part of developing new and relevant applications is staying on top of current events, which can mean reading through a lot of news articles. The one topic we run into most often, especially recently here in Ohio, is hydraulic fracturing. Recently, the governor of Ohio announced increased fees for dumping wastewaters associated with hydraulic fracturing from out of state sources. All implications are that these drilling activities will have a national as well as global impact, as evident by this map of the shale gas plays in North America.
