Minerals may undergo recrystallization reactions in low temperature (< 100° C) aqueous
systems, during which they exchange isotopes and trace elements with the dissolved …

The development of reactive transport soared during the 1990's, driven by the necessity to
demonstrate the long-term efficiency of radioactive waste repositories (Bildstein et al. 2019; …

Wastewaters from oil and gas development pose largely unknown risks to environmental
resources. In January 2015, 11.4 ML (million liters) of wastewater (300 g/L TDS) from oil …

The development of unconventional oil and gas (UOG) resources has rapidly increased in
recent years; however, the environmental impacts and risks are poorly understood. A single …

Calcite and aragonite growth rate experiments have been performed in the presence of
aqueous Ba at 25° C using the constant addition technique as a function of CaCO 3 mineral …

The colloidal transport of trace (Fe, Al, Ba, Pb, Sr, U) and ultra-trace (226 Ra) elements was
studied in a mining environment. An original approach combining 0.45 μm filtered water …

In the western US, produced water from oil and gas wells discharged to surface water
augments downstream supplies used for irrigation and livestock watering. Here we …

Sparingly soluble sulfate minerals, particularly barite (BaSO4), present an ideal system to
understand mineral–water interfacial reactions. The model system barite has been used to …

The kinetics of crystal growth in porous media controls a variety of natural processes such as
ore genesis and crystallization induced fracturing that can trigger earthquakes and …

Thermodynamic properties of mixing in the ternary (Ba, Sr, Ra) SO 4 solid solution are
determined using first principles based total energy calculations and Monte Carlo …
