Elevated concentrations of per-and polyfluoroalkyl substances (PFAS) in drinking-water
supplies are a major concern for human health. It is therefore essential to understand factors …

Managed aquifer recharge (MAR) systems can be designed and operated to improve water
supply and quality simultaneously by creating favorable conditions for contaminant removal …

The hyporheic zone (HZ), where surface water and groundwater interact in sediments
beneath streams, presents unique conditions for nutrient dynamics, such as carbon and …

The sediment–water interfaces (SWI) of streams serve as important biogeochemical
hotspots in watersheds and contribute to whole-catchment reactive nitrogen budgets and …

Nitrogen dynamic in a hyporheic zone (HZ) is mediated by microbes in the form of biofilms
attached to sediment grains. Previous studies have neglected the influence of microbial …

Lough Gur is a shallow groundwater fed eutrophic lake situated within a small agricultural
catchment containing volcanic and karst rock features in mid‐west Ireland. Seasonally active …

Biogeochemical processes are often spatially discrete (hot spots) and temporally isolated
(hot moments) due to variability in controlling factors like hydrologic fluxes, lithological …

Recent experimental studies have detected the presence of anoxic microzones in hyporheic
sediments. These microzones are small‐scale anoxic pores, embedded within oxygen‐rich …

Riverbank filtration is a natural aquifer-based process. The nitrogen dynamics in a riverbank
filtration system are affected by many factors, including temperature, water quality, and travel …

A unified conceptual framework for river corridors requires synthesis of diverse site‐, method‐
and discipline‐specific findings. The river research community has developed a substantial …
