Summary: Historical industrial activities have caused soil contamination at coastlines worldwide, which are susceptible to disruptions by climate change and rising sea levels. However, the effects of hydrologic dynamics on contaminant transportation in tidal environments have not been extensively studied. This research collected data from various sensors at a contaminated site near a freshwater tidal channel and found that seasonal groundwater interactions and sub-daily water level fluctuations in the channel contribute to varying redox conditions and contaminant concentrations. The findings highlight the importance of understanding the impacts of sea-level rise on the mobility of coastal solutes.

Summary: The importance of ecosystem services in water resources management has led to a focus on environmental-flows requirements for moving waters. However, current management practices often overlook the contribution of groundwater and fail to consider its importance in environmental flows. This study presents two methods for estimating groundwater environmental flow contributions, one based on groundwater and the other on surface water. The methods were tested in British Columbia, Canada and showed comparable results, suggesting their potential applicability in data-scarce, hydrologically complex landscapes globally.

Summary: In water-stressed hyperarid basins, the impacts of anthropogenic groundwater extraction and climate-driven perturbations on groundwater-surface water interactions and ecosystem-critical surface water are concerning. Utilizing Sentinel-2 data, the coupling of groundwater and surface water observations provides an opportunity to evaluate surface water connectivity in arid basins after intense precipitation events. The analysis of surface water area and groundwater level data shows varying connectivity between surface water change and groundwater fluctuations, with freshwater aquifers displaying some connectivity and brine-to-brackish areas exhibiting virtually none. The coupling of surface water and adjacent groundwater levels suggests that discharge via subsurface infiltration is the primary connection between local aquifers and surface water bodies. Modeled results also support the importance of marginal surface water systems as recharge mechanisms to local aquifers. Overall, these findings contribute to a better understanding of water availability and the resilience of surface water systems in water-stressed regions. Plain Language Summary

Summary: Over the past decades, hydrologic models have evolved from independent models to integrated models that can capture the entire terrestrial hydrologic cycle. These models have expanded to include various biogeochemical processes, sedimentation and erosion, human activities, and atmospheric processes. The development of these models has been driven by advancements in computing power, data availability, and understanding of the processes. Challenges include selecting appropriate models among many options and obtaining necessary data for parameterization and calibration. However, advancements in technology and data assimilation provide new ways to address these challenges. Furthermore, computational platforms and machine learning techniques support the use of larger and more complex models. It is important to develop accessible models that meet the needs of all users, not just researchers. Diverse modeling platforms should consider user needs, data availability, and computational resources.

Summary: Based on the analysis of 6131 stream sites across different land uses in the United States over a period of 27 years, it was found that macroinvertebrate density declined by 11% and richness increased by 12.2%. Insect density and richness showed even greater declines of 23.3% and 6.8%, respectively. Furthermore, there was an increasing difference in richness and composition between urban and agricultural streams compared to forested and grassland streams. Urban and agricultural streams lost disturbance-sensitive taxa and gained disturbance-tolerant taxa. These findings indicate that current stream protection and restoration efforts are insufficient to mitigate the impacts of human activities.

Summary: The open waters of large lakes can sometimes become depleted in important metals, causing growth limitation or metabolic function limitation in phytoplankton communities. Metal limitation has been observed in isolated waters with low metal supply relative to demand. It is possible that metal limitation could occur within algal blooms due to high demand and low availability of preferred forms of N and P. Laboratory incubation experiments on naturally occurring phytoplankton communities supported the hypothesis of metal limitation occurring in blooms, as low concentrations of metals and labile nutrients were often present. Metal amendments alone did not stimulate growth, but amendments of inorganic N and P resulted in increased chlorophyll. The study suggests that metal limitation may have important implications for phytoplankton communities in eutrophic nearshore areas.

Summary: A comprehensive study of stormwater runoff events at 21 sites across the United States measured 438 organic and 62 inorganic chemicals, revealing localized contamination with potential adverse effects on aquatic health. By assessing cumulative ratios of exposure-activity cutoffs and cumulative toxicity quotients, the study found moderate to high risks for acute adverse effects on aquatic organisms across multiple trophic levels near stormwater discharge points. However, these results are likely significant underestimations of actual risk due to the limited number of compounds analyzed compared to those in commercial use and potential metabolites.
