The U.S. EPA has posted a 25-page summary of the five technical roundtables held in November 2012 to help inform its Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. The roundtables focused on a different stage of the hydraulic fracturing water cycle:
- Water acquisition
- Chemical mixing
- Well injection
- Flowback and produced water
- Wastewater treatment and waste disposal
The technical roundtables involved external subject-matter experts from a variety of stakeholder groups.
