Identifying sources and environmental risks of emerging mobile organic pollutants in the urban groundwater of Barcelona (Spain)

Environmental Chemistry and Ecotoxicology
Groundwater is a vital yet vulnerable resource, subject to contamination from recharge sources and water system leaks by organic pollutants, including personal care products, pharmaceuticals, sweeteners, and industrial chemicals.

Distribution and interaction between selected pharmaceuticals and hydrogeochemistry in Guadalhorce aquifer(South of Spain) [PDF]

, 2015
Management of water resources implies the study of their quality and in recent times one of the main drawbacks is the presence of non-regulated products, the so-called "Emerging Contaminants (EC)".

Arsenite sorption and co-precipitation with calcite [PDF]

, 2006
Sorption of As(III) by calcite was investigated as a function of As(III) concentration, time and pH. The sorption isotherm, i.e. the log As(III) vs.

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

Water 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.

Numerical modelling in support of a conceptual model for groundwater flow and geochemical evolution in the southern Outaouais Region, Quebec, Canada [PDF]

, 2017
A two-dimensional vertical-section numerical model for groundwater flow and transport using age, tritium and chloride was used to help validate a conceptual model of geochemical evolution within a representative regional-scale hydrogeological system in ...

Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Reservoirs are vital tools for managing riverine water resources but also influence water quality through in‐lake nutrient (i.e., nitrogen [N] and phosphorus [P]) dynamics that affect downstream ecosystems. This study presents a multiscale spatiotemporal characterization of water quality in Carlyle Lake, an agriculturally impacted reservoir in

Hydrochemical Characteristics of High‐Temperature Geothermal Fluids and Quantitative Assessment of Wellbore Scaling in the Yangbajain Geothermal Field, Tibet

Geofluids, Volume 2026, Issue 1, 2026.
Severe calcium carbonate scaling occurs in the wellbores of high‐temperature geothermal wells in the Yangbajain Geothermal Field. Based on sampling and laboratory analysis of the geothermal field, this study investigates the hydrogeochemical characteristics of the geothermal fluids, estimates the reservoir temperature, and reconstructs the bottom‐hole ...
