Inflow and Loadings from Ground Water to the Great Bay Estuary, New Hampshire [PDF]

open access: yes, 2004
This final report presents the results of a study to evaluate groundwater inflow and nutrient loadings to the Great Bay Estuary, New Hampshire. The evaluation of inflow was accomplished independently by two methods: one, used thermal imagery, and the ...

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

PFAS Vadose Zone Mass Discharge at an AFFF‐Impacted Site: 1. Validation Based on a Multiple Lines‐of‐Evidence Approach

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Questions have recently been raised about the suitability of using porewater samples collected with suction lysimeters to estimate per‐ and polyfluoroalkyl substances (PFAS) mass discharge in the vadose zone. Multiple lines of evidence were evaluated to determine if porewater samples collected during a data gaps investigation in the former ...

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

Renewing the Exploration Approach for Mid-Enthalpy Systems: Examples from Northern England and Scotland [PDF]

open access: yes, 2015
After a promising start in the 1970s and 80s, the UK rather fell behind other countries in the search for viable mid-enthalpy geothermal resources.

DNA‐ and RNA‐based microbial community diversity and composition in a deep agricultural subsurface environment

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Analysis of microbial community compositions in subsurface environments is essential because microbes significantly influence biogeochemical processes, including carbon storage, nutrient cycling, and groundwater quality. Many previous studies have relied on DNA‐based methods, which provide a robust taxonomic identification but can also ...

Monitoring of water volume in a porous reservoir using seismic data: Validation of a numerical model with a field experiment

open access: yesNear Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.
Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

Velocity estimation in GPR data based on diffraction analysis: Methodology and application to Antarctic firn

open access: yesNear Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.
Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...
