Lecture to focus on treatment of wastewater produced by gas drilling

Dave Yoxtheimer, EMS Extension Associate with the Marcellus Center for Outreach and Research, will discuss the wastewater stream -- commonly known as flowback water -- that is associated with hydraulic fracturing of natural gas-bearing shales in Pennsylvania. His talk, "Treatment and Disposal of Wastewater from Natural Gas Drilling in Pennsylvania," will take place from noon to 1 p.m. in room 302 of the Pond Laboratory on Penn State's University Park campus.

Recent news reports have indicated that the majority of the flowback water is partially treated and then released to surface waters utilized for drinking water at downstream locations. This has raised water quality concerns to downstream users. Yoxtheimer will examine existing treatment technologies and their effectiveness in removing contaminants. He also will address the implications of Pennsylvania’s new wastewater treatment regulations for water quality and the increased use of wastewater by the industry.
