Nitrate occurrence, alternative management practices, and modeled transport in the vadose zone over Nebraska's High Plains Aquifer

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Groundwater contamination by nitrate (NO3‐N) is a growing environmental and public health concern for the High Plains Aquifer underlying Nebraska, which is driven largely by intensive agricultural fertilizer applications. However, uncertainty remains in the variability of nitrate concentrations across deep vadose zones and the potential for ...

Evaluating the effect of compaction on soil hydraulic properties

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Soil compaction is commonly viewed by agronomists as an undesirable consequence of intensive agricultural activities arising from heavy machinery or livestock trampling. However, deliberate compaction of the furrow bottom has been considered as a potential water management practice to reduce deep percolation losses and improve furrow ...

Reliability‐Based Evaluation of the Robustness of Constructed Wetlands for Sustainable Sanitation: Implications for Design and Operation

Water Environment Research, Volume 98, Issue 9, September 2026.
Reliability analysis of 34 constructed wetlands showed wide operating margins for organic matter and suspended solids, but less frequent sustained compliance for nitrogen and phosphorus. Robustness should therefore be assessed using system‐ and parameter‐specific reliability, together with removal efficiency and final effluent concentration.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Dams and Their Legacies Shape Biogeochemical Evolution of Riparian Sediments

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Dams and their legacies have substantially altered riparian ecosystems worldwide and these effects could persist for decades or centuries into the future. However, how biogeochemical characteristics of riparian sediments evolve with depth and time post dam removal is poorly understood.
