Matrix-Derived Radium Mobilization in Shallow Aquifers Near Unconventional Oil and Gas Operations

Allison Fenske, Jianfeng Su, Jennifer Baka, Brandon Forsythe et autres

Previous studies in Pennsylvania identified localized "hotspots" of elevated salinity (Cl-, Ba2+, Sr2+) in shallow groundwater thought to be associated with unconventional oil and gas (UOG) operations. Because produced water generated during UOG operations is both highly saline and enriched in radium, …

A short-term critical zone geophysics program designed to recruit, retain, and foster community amongst 1st and 2nd year undergraduates historically marginalized in geosciences

Kristina Keating, Kristin O’Connell, G. Mount, J. L. Hayes et autres

The Geophysics of the Near Surface: an Outdoor Motivational Experience for Students, or GNOMES, program was designed to recruit, engage, and retain racially and ethnically minoritized students early in their undergraduate experience into geoscience. This goal was enacted by introducing a diverse …

Wastewaters Coproduced with Shale Gas Drive Slight Regional Salinization of Groundwater

Samuel Shaheen, Tao Wen, Zhong Zheng, Lingzhou Xue et autres

While unconventional oil and gas (UOG) development is changing the world economy, processes that are used during UOG development such as high-volume hydraulic fracturing ("fracking") have been linked with water contamination. Water quality risks include leaks of gas and salty fluids (brines) …

Investigating the Roughness and Advance Rate of the Weathering Interface (Final Report)

Susan L. Brantley

To understand geological systems that are important to our national well-being -- such as nuclear waste repositories or hydraulically fractured rocks -- requires the ability to make quantitative projections of the evolution of rock-water systems forward in time. A fundamental goal of …

Using Homogenized Models to Explore the Effect of Fracture Densities on Weathering

Marina I. Lebedeva, Susan L. Brantley

Despite its importance, only a few researchers have incorporated the effects of fracturing into models of reactive transport for rock weathering. Here we explore 2D simulations that describe weathering under conditions of diffusive and advective transport within heterogeneous media consisting of rocky …
