Significant progress in hydrology, especially in subsurface flow and solute transport, has
been made over the last 35 years because of sustained interest in underground nuclear …

Reactive transport (RT) couples bio-geo-chemical reactions and transport. RT is important to
understand numerous scientific questions and solve some engineering problems. RT is …

Evaluating the proportion in which waters from different origins are mixed in a given water
sample is relevant for many hydrogeological problems, such as quantifying total recharge …

Modeling transport of reactive solutes is a challenging problem, necessary for
understanding the fate of pollutants and geochemical processes occurring in aquifers, rivers …

This work presents the occurrence and fate of selected personal care products (PCPs) in the
urban river–groundwater interface. To this end, urban river and groundwater samples were …

Total and dissolved rare earth elements (REE) were studied in a river reach affected by
several inputs of acid mine drainage. The first four acidic discharges were of lesser …

Urban aquifers are at risk of contamination from persistent and mobile organic compounds
(PMOCs), especially per-and polyfluoroalkyl substances (PFAS), which are artificial organic …

Pharmaceuticals, such as non-steroidal anti-inflammatory drugs (NSAIDs) and their
metabolites, have become a major concern due to their increasing consumption and their …

Chemical reactions are driven by disequilibrium, which is often caused by mixing. Therefore
quantification of the mixing rate is essential for evaluating the fate of solutes in natural …

Understanding the mixing between surface water and groundwater as well as groundwater
travel times in vulnerable aquifers is crucial to sustaining a safe water supply. Age dating …
