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

Water and Environment Journal, Volume 40, Issue 3, Page 357-366, August 2026.
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.

Groundwater Geochemistry in the Karst-Fissure Aquifer System of the Qinglian River Basin, China

Hydrology
The Qinglian River plays a significant role in China’s national water conservation security patterns. To clarify the relationship between hydrogeochemical properties and groundwater quality in this karst-fissure aquifer system, drilling data ...

Tracking Spatiotemporal Mineral Dissolution Through Quantitative Nuclear Magnetic Resonance Signatures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mineral dissolution reorganizes pore space through spatiotemporally variable pathways, but non‐invasive tracking remains difficult. We test whether nuclear magnetic resonance (NMR) signatures can diagnose carbonate dissolution by integrating pore‐scale reactive transport simulations with forward modeling of T2 ${T}_{2}$ distributions for face ...

Tracing Nitrate Contamination Sources and Transformations in a Rural−Urban Karst Groundwater System in North China Using Multiple Isotopes and Simmr Modeling

Water Resources Research
In temperate karst aquifers under intensive anthropogenic impacts and high heterogeneity, groundwater contamination tracking has predominantly focused on nitrate, but inadequate evidence for co‐occurring ammonium sources undermines accurate nitrogen ...

Global‐Scale Groundwater Recharge Modeling Is Improved by Tuning Against Ground‐Based Estimates for Karst and Non‐Karst Areas

Water Resources Research
Quantification of groundwater recharge is highly important for understanding freshwater systems and sustainable management of both groundwater and surface water bodies, but it is very uncertain.

Genesis analysis of karst groundwater inrush and prediction of its water inflow in the Huxitai Tunnel

Carsologica Sinica
Tunnel water inrush is one of the primary threats to tunnel construction safety, not only posing risks during the construction but also creating long-term hidden dangers for the post-construction operation and maintenance.

Analysis of the formation mechanism of karst collapse in the Panlong lead-zinc mine, Wuxuan, Guangxi

Carsologica Sinica
Karst collapse is a major geological hazard in karst areas, characterized by suddenness and concealment. Over the years, human engineering activities-such as mining at the Panlong lead-zinc mine in Wuxuan, Guangxi, and the impoundment of the Datengxia ...
