TL;DR: In this article, the multivariate statistical techniques principal component analysis (PCA), Q-mode factor analysis (QFA), and correspondence analysis (CA) were applied to a dataset containing trace element concentrations in groundwater samples collected from a number of wells located downgradient from the potential nuclear waste repository at Yucca Mountain, Nevada.

TL;DR: In this article, the rare earth elements (REE) were analyzed in a groundwater system from south-central Nevada (i.e., Ash Meadows National Wildlife Refuge, the Spring Mountains, Pahranagat National wildlife Refuge, and the Nevada Test Site) in order to investigate their potential use as tracers of regional groundwater flow.

TL;DR: In this article, rare earth element (REE) concentrations were determined in circumneutral pH (7 ≤ pH ≤ 9) groundwaters from south-central Nevada and the Mojave Desert in eastern California, U.S.A.

TL;DR: In this article, the authors measured the concentration of rare earth elements (REE) in groundwaters from southern Nevada and Death Valley, CA and demonstrated that carbonate complexes dominate REE speciation in these groundwaters.

TL;DR: In this paper, an ICP-MS with an ultrasonic nebulizer and an active-film multiplier detector was used to determine 54 trace elements directly in ground water, including lithium, arsenic, rubidium, strontium, barium, and antimony.
