Long‐Term Discharge Records from United States and European Karst Springs: Data Limitations in Trend Analysis

Groundwater, EarlyView.
Karst spring discharge trend (the change in discharge over a period greater than 30 years for each spring) does not depend on discharge variability. Insets show two springs with contrasting discharge variability (variable vs. extremely high variability) but similar discharge trends.

Geospatial and AHP based identification of potential zones for groundwater recharge in Haridwar District of India

Frontiers in Environmental Science
Demarcation of the groundwater recharge prospective zones can be the foremost step in facilitating groundwater recharge in any terrain, as most nations have a major concern about unreasonable use of groundwater and declining the water table.

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites

Groundwater Monitoring &Remediation, EarlyView.
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Impacts of seasonal vegetation dynamics on water balance and groundwater recharge: a monthly leaf area index (LAI)-driven WetSpass-M application in the Sapgyocheon basin, South Korea

Applied Water Science
Groundwater recharge is a key indicator for sustainable groundwater use and water resources management. Although groundwater recharge depends on climatic and land-surface conditions, previous WetSpass-M applications have often underestimated the role of ...

In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, EarlyView.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

Groundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

Computationally Efficient Ranking of Sampling Locations by Redundancy in Groundwater Monitoring Networks

Groundwater Monitoring &Remediation, EarlyView.
Abstract The long‐term and frequent sampling of groundwater monitoring networks is common practice for monitoring the concentrations of constituents of potential concern (CoPC) over space and time. Sampling can be a costly and time‐intensive process that also incurs health and safety risks. A redundancy‐based ranking of candidate sampling locations can
