Chlorinated ethenes (CEs) are legacy contaminants whose chemical footprint is expected to
persist in aquifers around the world for many decades to come. These organohalides have …

Bank filtration (BF) has been employed for more than a century for the production of water
with a better quality, and it has been showing satisfactory results in diclofenac attenuation …

Interpreting the fate of wastewater contaminants in streams is difficult because their inputs
vary in time and several processes synchronously affect reactive transport. We present a …

Stream networks can retain or remove nutrient pollution, including nitrate from agricultural
and urban runoff. However, assessing the location and timing of nutrient uptake remains …

This study characterized the hyporheic zone of a stretch of the Ipojuca River through
analysis of the sediments and meiofauna of this environment. Samples were collected at two …

Lotic systems are a prominent ecohydrological interface within which complex, coupled
interactions occur between ecological, hydrological, and geochemical processes. This …

The evasion of greenhouse gases (including CO2, CH4, and N2O) from streams and rivers
to the atmosphere is an important process in global biogeochemical cycles, but our …

The mean transit time (MTT) is a fundamental property of a groundwater flow system that is
strongly related to the ratio of recharge rate to storage volume. However, obtaining samples …

Abstract Surface water (SW)-groundwater (GW) interactions exhibit complex spatial and
temporal patterns often studied using tracers. However, most natural and artificial tracers …

Using continuous injections of helium coupled to in-situ continuous flow membrane inlet
mass spectrometry (CF-MIMS), we mapped the gas exchanges along two low-slope …
