The GSI Board is pleased to announce the promotion of Mr. Travis McGuire, PE, to President of GSI, effective January 1, 2023.

Travis brings over 20 years of outstanding service to our commercial, industrial, and R&D clients, as well as the successful leadership and growth of our Houston office and corporate finance team. John Connor, our President for nearly four decades, will remain with our team as a Senior Principal and a board member. Travis and John look forward to continuing the exceptional level of service, expertise, and innovation upon which our clients rely.

GSI is honored and thrilled to formally announce that Dr. Sorab Panday received the Lifetime Achievement Award from the Groundwater Resources Association of California for his work in subsurface modeling and analysis, being a good guy, and all around smarty pants.   The photo below captures the moment when Dr. Chin Man Mok presented him the award.  Two of the greatest groundwater nerds we have the pleasure to have apart of GSI!

New developments in the CCUS world! POTUS signs the Inflation Reduction Act (IRA) thereby expanding financial incentives and timeframes for CCUS projects! Other new incentives in the IRA include provisions for direct payment in lieu of tax credits and the ability for project owners to transfer credits.

Exciting times ahead for CCUS! Read more on the flyer below 👇👇👇

🌟🌟 #WINNING GSI-Sponsored Senior Design Project at Rice University on Novel PFAS Treatment Wins the Excellence in Capstone Engineering Design Award! #PFAS #environmental #innovation

GSI Environmental Inc. established a new method for concentrating per- and polyfluoroalkyl substances (PFAS) that relies on colloidal gas aphrons (CGAs), unusual microstructures composed of water, multilayers of surfactants, and air, that can be used for separation and concentration of PFAS-impacted water (Newell et al., 2021, patent pending; Kulkarni et al., 2022). In the recently published study by GSI and Clarkson University, in small batch systems, CGAs were effective in the removal of both ionic dyes (as proxies for PFAS), as well as short-chain PFAS (Kulkarni et al., 2022).

As a follow-on GSI-sponsored project, Rice University’s Oshman Engineering Design Kitchen team designed a continuous flow CGA system for ex-situ PFAS treatment. The automated system was successful using methylene blue dye as a proxy for PFAS, and consisted of:
– ~1 gpm continuous flow of impacted water through a separation reactor
– Generation of CGAs, verified using microscopy
– Continuous removal of concentrated PFAS/CGA layers
– 96% removal of methylene blue dye in effluent of reactor

Due to their clever design and successful execution, the team won the Excellence in Capstone Engineering Design Award! We thank the team members and look forward to continued support of the Oshman Engineering Design Kitchen at Rice University.
