The Ground Water Protection Council (GWPC) is pleased to provide an updated version of our 2009 report on U.S. Produced Water Volumes and Management Practices. This 2015 report, which contains data for 2012, discusses the amounts of water brought to the surface during oil and gas production and details many of the current minimization, treatment, re-use and disposal protocols used to manage produced water. It also contains state by state produced water summaries. The report was developed for the GWPC by John Veil of Veil Environmental, LLC. We think you will find this report both thorough and valuable.
