Tracer testing is a mature technology used for characterizing aquatic flow systems. To gain
more insights from tracer tests a combination of conservative (non-reactive) tracers together …

Chlorinated solvents such as trichloroethene (TCE) and tetrachloroethene (PCE) are
widespread groundwater contaminants often released as dense nonaqueous phase liquids …

Can we hope for autonomous (self-contained in situ) sensing of subsurface soil and
groundwater pollutants to satisfy relevant regulatory criteria? Global advances in sensors …

This pore-scale modeling study in saturated porous media shows that compound-specific
effects are important not only at steady-state and for the lateral displacement of solutes with …

Interest in using contaminant mass discharge (CMD) for risk assessment of contaminated
sites has increased over the years, as it accounts for the contaminant mass that is moving …

The estimation of mass discharges from contaminated sites is valuable when evaluating the
potential risk to down‐gradient receptors, when assessing the efficiency of a site …

In porous media, lateral mass exchange exerts a significant influence on the dilution of
solute plumes in quasi steady state. This process is one of the main mechanisms controlling …

Quantitative knowledge of contaminant mass discharge is useful when assessing the risk
posed to streams by point sources. However, due to a multi-directional flow field at the …

This volume is meant to provide the practitioner with information on the natural mixing
processes occurring in aquifers as well as to describe basic strategies that can be …

Attenuation processes of chlorinated ethenes in complex near-stream systems result in site-
specific outcomes of great importance for risk assessment of contaminated sites. Additional …
