You are cordially invited to join my office for a briefing by the authors of a new study in the Proceedings of the National Academy of Sciences related to oil and gas development and drinking water contamination on Friday, June 5th at 11:00 AM in Rayburn 2322.

Oil and gas production enabled by horizontal drilling and hydraulic fracturing continues to increase, and the potential environmental impacts are still not well understood. A team of researchers in Pennsylvania recently released a study of a drinking water contamination incident attributed to Marcellus Shale gas development. Please join us as they provide an overview of their key findings and the cutting-edge techniques they used to identify specific contaminants found in drinking water wells in the Marcellus Shale region. This briefing will also give insight into how researchers are working to understand pathways to contamination from oil and gas development and the inherent complexity of these endeavors.

Speakers at this briefing will include:

Garth T. Llewellyn, PG, LSRP
Principal Hydrogeologist
Appalachia Hydrogeologic and Environmental Consulting, LLC

Dave Yoxtheimer, PG
Extension Associate
Penn State
Marcellus Center for Outreach and Research Penn State University

Frank L. Dorman, PhD
Associate Professor, Biochemistry and Molecular Biology
Penn State University

Please contact Eleanor Bastian (eleanor.bastian@mail.house.gov) or Ellen Treimel (ellen.treimel@mail.house.gov) with any questions.

Sincerely,

Diana DeGette
