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.

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Modeling the configuration of karst aquifers underlain by volcanic rocks using satellite gravimetry: insights from the Gunungsewu karst area, Indonesia

open access: yesIndonesian Journal of Geography
The satellite gravimetry method has been employed for subsurface configuration modeling, delineating structures and boundaries of an aquifer, and determining an aquifer layer in a wide range of geological formations.

Role of Unsaturated Zone on Aquifer Leakage–Assessed With Tidal Response

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tidal response analysis is widely used to evaluate aquifer systems, but traditional models that neglect the unsaturated zone often underestimate groundwater leakage. This study develops a new analytical model for tidal analysis that incorporates unsaturated zone effects and explained leakage patterns that traditional models could not resolve ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Mobile sediments in a karst aquifer [PDF]

open access: yes, 1997
In karst aquifers, mobile sediments may play a fundamental role in determining water quality by concentrating and transporting contaminants. This study investigates spatial characteristics of sediment in a karst aquifer, examines temporal characteristics
