An in-situ colloidal activated carbon barrier is treating PFAS at an Army National Guard site in Michigan. Colloidal activated carbon was selected because it rapidly reduces PFAS by removal from the dissolved mobile phase, and results in lower total project costs when compared to operating a mechanical system.

Recent geophysical and petrological observations indicate the presence of water and hydrous melts in and around the mantle transition zone (MTZ), for example, prominent low-velocity zones detected by seismological methods. Experimental data and computational predictions describe the influence of water on elastic properties of mantle minerals. Using thermodynamic relationships and published databases, we calculated seismic velocities and densities of mantle rocks in and around the MTZ in the presence of water for a plausible range of mantle potential temperatures.

Along subduction interfaces or some major faults, a seismogenic layer in the upper crust is underlain by a zone of slow-slip events (SSEs) and tremors, and seismicity disappears at greater depths. The transition between seismogenic and aseismic behavior may be caused by changes in the frictional properties of the fault or changes in viscoelastic properties of the surrounding medium. Although aseismic transients have been numerically generated in previous studies by changing the frictional properties and compared to SSEs, the effect of viscoelasticity on the transition remains to be studied.

Little bits of black carbon littering the ocean floor, separate and distinct from the organic carbon believed to come from the ocean's surface. The source of that strange, and older, carbon has now been identified. The discovery is an important step in understanding the marine carbon cycle.

For the first time, astronomers have gotten an up-close view of eruptions from an asteroid, shedding light on what might drive such explosions.
The findings suggest that many asteroids may be similarly active and reveal that rocks blasting off of asteroids may be a new way for meteorites to reach Earth, the scientists wrote in a new study.

Something strange happened in the Late Triassic. About 232 million years ago, during a span known as the Carnian age, it rained almost everywhere. After millions of years of dry climates, Earth entered a wet period lasting one million to two million years. Nearly any place where geologists find rocks of that age, there are signs of wet weather. This so-called Carnian pluvial episode coincides with some massive evolutionary shifts.
Perhaps most dramatically, the Carnian pluvial might have overlapped with when a rare group of reptiles — early dinosaurs — evolved into a diverse group and came to dominate land ecosystems.

A new study determined that the Earth's crust in southern Arizona was once almost 60 kilometers thick, which is twice as thick as it is today — and comparable to how thick the crust is in parts of the Himalayas. This work has implications for the distribution of natural resources, such as copper, and provides insight into the formation of mountains during the subduction of tectonic plates.

In source regions of magmatic systems the temperature is above solidus, and melt ascent is assumed to occur predominantly by two-phase flow, which includes a fluid phase (melt) and a porous deformable matrix. Since McKenzie (1984) introduced equations for two-phase flow, numerous solutions have been studied, one of which predicts the emergence of solitary porosity waves.

New research from the University of Otago has found the sensitive West Antarctic Ice Sheet collapsed during a warming period just over a million years ago when atmospheric carbon dioxide levels were lower than today.

The 1930 discovery of Carboniferous lycopsid fossils in south central Colorado resulted in the naming of a new species of scale tree, Lepidodendron johnsonii (Lepidopholios johnsonii (Arnold) DiMichelle). Cellular structuresof L. johnsonii axes and periderm are preserved in silica — an unusual mode of fossil preservation for Pennslyvanian lycopsid plant remains. The early reports on the Trout Creek lycopsid fossils focused on taxonomic and paleobotanical aspects. Our 2019 reinvestigation of the locality produced many new specimens and a wealth of new data from a variety of analytical methods.
