Critic of Drilling Will Leave Job at Pitt

Conrad Volz, director of the University of Pittsburgh's Center for Healthy Environments and Communities, is leaving his position, saying that the university wants him to focus on teaching and research, and not to be an advocate in environmental debates, The Pittsburgh Tribune-Review reported. (He has been a critic of Marcellus shale drilling, and has drawn fire from its supporters.) University officials did not respond to a request for comment.
