Ongoing controversy over Pennsylvania's oversight (or lack thereof) of fracking for gas in the Marcellus Shale has brought a lot of readers to the Pittsburgh Post-Gazette's "Pipeline" reporting portal. The Post-Gazette offers interactive maps of drilling data from the Department of Environmental Protection. One big problem: "DEP's production data ... says there are 495 more wells producing gas, or ready to produce gas, than DEP has recorded as ever being drilled, and 182 of those wells don't even show up on the state's Marcellus Shale permit list."
