This dataset provides groundwater age estimates for 203 wells used as public- and domestic-supply in two selected areas of California. Groundwater ages were estimated by calibration of...
-
Groundwater age distributions and susceptibility to natural and anthropogenic contaminants were assessed for selected wells across Minnesota. The data provide information to understand how long it...

Fish age validation with bomb-produced radiocarbon (14C) requires a known-age Delta14C reference chronology spanning the era of a marine increase in bomb-produced 14C (1950s to 1960s). Concordance...

We computed mean groundwater ages and age distributions at eight wells by calibrating lumped parameter models (LPMs) to concentrations of tracers (3H, CFCs, SF6) in samples using the computer...
