Limitations of the use of environmental tracers to infer groundwater age

JL McCallum, PG Cook, CT Simmons - Groundwater, 2015 - Wiley Online Library
Apparent ages obtained from the measured concentrations of environmental tracers have
the potential to inform recharge rates, flow rates, and assist in the calibration of groundwater …

Partitioning young and old groundwater with geochemical tracers

S Jasechko - Chemical Geology, 2016 - Elsevier
Groundwater age—defined as the time elapsed since the groundwater entered the
subsurface—is a helpful indicator of groundwater quality and renewal. Some tracer-based …

Solute reactive tracers for hydrogeological applications: a short review and future prospects

V Cao, M Schaffer, R Taherdangkoo, T Licha - Water, 2020 - mdpi.com
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 …

Evaluation of high-frequency mean streamwater transit-time estimates using groundwater age and dissolved silica concentrations in a small forested watershed

NE Peters, DA Burns, BT Aulenbach - Aquatic geochemistry, 2014 - Springer
Many previous investigations of mean streamwater transit times (MTT) have been limited by
an inability to quantify the MTT dynamics. Here, we draw on (1) a linear relation (r 2= 0.97) …

Comparison of groundwater age models for assessing nitrate loading, transport pathways, and management options in a complex aquifer system

EH Koh, E Lee, D Kaown, CT Green… - Hydrological …, 2018 - Wiley Online Library
In an aquifer system with complex hydrogeology, mixing of groundwater with different ages
could occur associated with various flow pathways. In this study, we applied different …
