We’re excited to announce the 2015 update to our Pennsylvania FrackFinder data set! Using the USDA’s most recent high-resolution aerial imagery for Pennsylvania, we’ve updated our maps of the state’s drilling sites and wastewater impoundments. Our revised maps show Pennsylvania’s drilling sites and wastewater impoundments as of Fall 2015.
Our previous Pennsylvania FrackFinder project identified the location of active well pads in imagery from 2005, 2008, 2010 and 2013. We are pleased to add the 2015 update to this already rich data set.
The goal of our FrackFinder projects has always been to fill the gaps in publicly available information related to where fracking operations in the Marcellus and Utica Shale were taking place. Regrettably, there are often discrepancies between what’s on paper and what’s on the landscape. Permits for individual oil and gas wells are relatively accessible, but the permits are just approvals to drill: they don’t say if a site is active, when drilling and fracking began or ended, or if development of the drill site ever happened at all.
We compared permit locations against high-resolution aerial imagery from the USDA’s 2015 National Agricultural Inventory Program (NAIP) to determine whether drilling permits issued since the close of our last Pennsylvania FrackFinder project in 2013 were active. There were more than 4,500 drilling permits issued in Pennsylvania during our study period (May 1, 2012, to September 30, 2015), many of them located quite close together. Ultimately, we ended up with roughly 2,000 unique ‘clusters’ of drilling permits to investigate and map.
We look forward to seeing how the public will use these revised data sets. We hope researchers, NGOs and community advocates can use these unique data sets to gain a better understanding of the impact of fracking on Pennsylvania’s environment and public health.
