Microbial Communities in Sediments From Different Landform Systems, Svalbard

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Svalbard is host to a range of glacier types with different thermal regimes, behaviors and complex hydrological networks and landforms. Here, we hypothesize that the (H1) surge‐type glaciers will host different microbial community structures, and that (H2) different landform types will also host different microbial community structures.

Tracing Nitrate Contamination Sources and Transformations in a Rural−Urban Karst Groundwater System in North China Using Multiple Isotopes and Simmr Modeling

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract In temperate karst aquifers under intensive anthropogenic impacts and high heterogeneity, groundwater contamination tracking has predominantly focused on nitrate, but inadequate evidence for co‐occurring ammonium sources undermines accurate nitrogen pollution assessments.

Comparison of Real Versus Synthetic NOM on Lead and Copper Release Using Dump and Fill Studies

open access: yesAWWA Water Science, Volume 7, Issue 5, September/October 2025.
ABSTRACT The main objective of this study was to evaluate and compare the impact of real and synthetic NOM on lead and copper release from galvanic corrosion. A 21‐week “dump and fill” experiment was completed using test pieces with new lead and copper pipes exposed to various drinking waters.
