A new publication examines how microbial processes may influence the fate of CO2 in geologic carbon sequestration settings.

The article, Biotransformation Processes Relevant to Geologic Carbon Sequestration: Potential Implications for Environmental Fate, is published in Environmental Science & Technology and is authored by GSI experts Lisa J. Molofsky, Thomas E. McHugh, Danny Kingham, and Charles J. Newell, with contributions from Sven Lahme, Kelly M. McFarlin, Paul G. Koster van Groos, Frank E. Löffler, Louise Camenzuli, Leanne Walker, Sophie L. Nixon, and Trent A. Key.

The paper reviews how CO2-driven geochemical changes can alter microbial communities and trigger biotransformation processes that move carbon into mineral, gas, or organic phases. It also explores implications for both deep storage formations and nontarget environments such as shallow groundwater, the vadose zone, and marine systems, while identifying key knowledge gaps that affect long-term prediction of CO2 behavior.

Congratulations to Dr. Gino Bianchi Mosquera, PG, BCES, on the publication of “Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume,” in Groundwater Monitoring & Remediation.

This open access article, co-authored with D. M. Mackay, B. Myller, B. D. Honeyman, M. Schirmer, R. M. Allen-King, W. P. Ball and R. L. Stollar, presents findings from a field experiment at the Rocky Mountain Arsenal evaluating organic contaminant transport within a complex plume. The study provides new insight into why contaminants may migrate with little to no sorptive retardation in situ and identifies the need for additional laboratory research to better understand the plume components that influence sorption and mobility.

A combined 228Ra/226Ra and 87Sr/86Sr approach to identify the production of out-of-zone formation fluid from Marcellus shale gas wells

Lisa Molofsky, PhD, PG has co-authored a new article titled "A combined 228Ra/226Ra and 87Sr/86Sr approach to identify the production of out-of-zone formation...

Lisa Molofsky, PhD, PG has co-authored a new article titled “A combined 228Ra/226Ra and 87Sr/86Sr approach to identify the production of out-of-zone formation fluid from Marcellus shale gas wells,” published in Applied Geochemistry.

This article, co-authored with M.A. Engle, T.W. Wagner, A.S. Wylie, and D.P. Fernandez, presents a geochemical method that combines radium and strontium isotope ratios to determine the origin of high-salinity fluids produced from Marcellus shale gas wells. The study provides valuable insights into identifying out-of-zone water production and offers a framework that could be applied to other oil and gas basins.
