Groundwater May Fix as Much Carbon as Some Ocean Surface Waters
Microbes from wells as deep as 90 meters created organic carbon at a rate that overlaps with some nutrient-poor spots in the ocean.
Protecting Children’s Health Can Benefit the Economy
A new study presents an integrated approach to predicting the human health impacts, economic implications, and remediation solutions for using contaminated groundwater in Central Mexico.
Los microbios podrían comer minerales magnéticos en un sitio de derrame de petróleo
Nuevos experimentos en un antiguo sitio de derrames de petróleo en Minnesota sugieren que los procesos no biológicos por sí solos no pueden explicar la disminución de la magnetización.
Microbes Might Munch Magnetic Minerals at Oil Spill Site
New experiments at an old oil spill site in Minnesota suggest that nonbiological processes alone may not account for decreased magnetization.
Shedding Light on Microbial Communities in Deep Aquifers
Researchers use a packer system to study the microbial communities living in waters sampled from deep, uncontaminated peridotite aquifers.
Dyes and Isotopes Track Groundwater from Sink to Spring
The hydraulic connection between a sinkhole and a natural spring—the longest and largest yet documented—could help reduce the guesswork in mapping karst aquifers.
Tracing Water from River to Aquifer
A new technique using dissolved noble gas tracers sheds light on how water moves through an aquifer, with implications for water resources and their vulnerability to climate change.
Parsing Routes to Aquifer Recharge Along Mountain Fronts
Research from the Tucson Basin indicates that tracers can be used to distinguish surface and subsurface recharge, providing crucial data to support sustainable water management in arid environments.
Modeling Groundwater and Crop Production in the U.S. High Plains
Innovative new research by a team of international scholars borrows modeling methods from ecology and applies them to groundwater sustainability.
