"PITTSBURGH - As Marcellus Shale activity sweeps Western Pennsylvania, a new University of Pittsburgh database reveals that approximately 7 percent of Allegheny County's land has been leased for drilling and extraction since 2003. In addition, the number of properties in the county leased for oil and gas exploration increased by 322 percent between 2008 and 2009.
Researchers in Pitt's University Center for Social and Urban Research (UCSUR) used leases filed with the Allegheny County Department of Real Estate to create an interactive map of the more than 2,000 parcels in Allegheny County leased for oil and gas exploration between 2003 and May 2010. The map also indicates the people or companies that bought the leases. The map is available on UCSUR's Web site at www.ucsur.pitt.edu/thepub.php through the Pittsburgh Urban Blog, or the PUB, a new service established by UCSUR to make research on regional statistics and trends readily available. It was created by the Pittsburgh Neighborhood and Community Information System (PNCIS), Pitt's online database of statistical maps." More>>>>
