May Presentation

Evolution of an Expansive Contaminant Plume - Naval Weapons Industrial Reserve Plant Bethpage, Long Island, New York



Brian S. Murray PG, PMP



Past operations at the former Naval Weapons Industrial Reserve Plant located in Bethpage, New York (NWIRP Bethpage) resulted in the release of volatile organic compounds to groundwater. The resulting large plume has evolved and dispersed due to several factors including: a highly transmissive aquifer, a strong natural gradient to the south, past operation of groundwater production wells by Northrop Grumman (plant operator for the Dept. of Navy), overlapping capture areas created by numerous public water supply wells, and ongoing (and planned) pump and treat remedial actions by the Dept. of Navy and Northrop Grumman. The successful restoration of groundwater by the Dept. of Navy must account for each of the factors influencing plume dispersion.



Mr. Murray is a retired Dept. of Navy Remedial Project Manager who was responsible for the execution the Navy's Environmental Restoration (ER) program at multiple Navy installations. Remedial Project Managers are tasked with execution of the ER program at each assigned installation. During his six-year employment with the Navy, Mr. Murray performed this role at Naval Weapons Station Earle (NJ), Naval Support Activity Mechanicsburg (PA), Naval Industrial Reserve Ordnance Plant Fridley (MN), Naval Submarine Base New London (CT), and lastly at Naval Weapons Industrial Reserve Plant Bethpage (NY). Mr. Murray executed his duties for the Naval Facilities Engineering Systems Command (NAVFAC), Mid-Atlantic Region, based in Norfolk, VA. Upon retirement, Mr. Murray was awarded the Dept. of Navy's third highest civilian award, the Navy Meritorious Civilian Service Award for his performance in execution of the Navy's ER program.

Mr. Murray is a registered professional geologist with 28+ years of experience managing CERCLA/RCRA site restorations with groundwater, soil, and sediment contamination. Mr. Murray earned BS and MS degrees in geology from the University of South Alabama and University of Alabama, respectively. Prior to Navy employment, Mr. Murray worked as a deputy division manager and senior hydrogeologist/project manager for Leidos in Oak Ridge, TN.




Greetings! We hope you will join us for the next ETGS virtual meeting, and that you, your family, and your colleagues are staying healthy and well. 

As a courtesy, please mute your cell phone or the microphone in your laptop/tablet to minimize background noise and feedback echoes. We will try to mute all participants until the presentation is finished. Please use the chat feature to type comments or questions during the presentation. We recommend that you send questions for the speaker to "everyone" so all participants can see the question. After the presentation, the speaker will answer questions.  During this Q&A period, you may unmute if you wish to ask a question verbally.

We will create an attendance list based on the participant names we can see during the meeting. This is helpful for those who need to document participation to support Professional Geologist registrations. It is not always possible to tell who is participating, especially for those joining by phone, so please email your name to etgs@live.com to be listed on the attendance sheet. Let us know exactly how your name should appear on the list.

Thank you for your patience and understanding as we continue adapting to this virtual format. As always, we welcome and appreciate your feedback and suggestions for improvement.
