The dynamic relationship between ground water and the Columbia River: Using deuterium and oxygen-18 as tracers The dynamic relationship between ground water and the Columbia River: Using deuterium and oxygen-18 as tracers

Deuterium and oxygen-18 were used as natural tracers to investigate the hydraulic relationship between the Columbia River and the Blue Lake gravel aquifer near Portland, Oregon. A time series of stable-isotope data collected from surface and ground waters during a March 1990 aquifer test confirms that the river and aquifer are hydraulically connected.
