Decadal Shifts in Groundwater Age Detected by Environmental Tracers Across California, USA

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Groundwater age offers important insight into recharge, storage, and contamination risk. Although models predict age changes can be driven by pumping and climate variability, direct observational evidence remains limited. Here, we analyzed paired environmental tracer suites (tritium, carbon‐14, and tritiogenic helium‐3) collected a decade ...
