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

open access: yes, 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]

open access: yes, 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.

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

open access: yesJAWRA 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

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, Volume 110, Issue 2, Page 135-150, December 2025.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

Mapping Arsenic Risks in the Ayeyarwady (Irrawaddy) Delta, Myanmar: Implications for Public Health

open access: yesGeoHealth, Volume 9, Issue 11, November 2025.
Abstract The Ayeyarwady Delta in Myanmar, home to an estimated 12 million people, faces widespread arsenic contamination similar to other Asian deltas namely Bengal, Red River, and Mekong. Arsenic here primarily results from reductive dissolution of iron minerals in anoxic conditions driven by organic carbon. Here, we used digital elevation model (DEM)

Chemical stimulation of geothermal reservoirs using retarded acid systems: current developments and potential directions

open access: yesGeothermal Energy
Stimulation techniques to enhance fluid pathways are an important tool to make geothermal projects economically feasible. So far, hydraulic stimulation is used almost exclusively for reservoir-wide improvement of the permeability, but induced seismicity ...

Hydrogeochemistry and isotope geochemistry of Velenje Basin groundwater

open access: yesGeologija, 2016
The geochemical and isotopic composition of groundwater in the Velenje Basin, Slovenia, was investigated between the years 2014 to 2015 to identify the geochemical processes in the major aquifers (Pliocene and Triassic) and the water–rock interactions.
