Mobile colloids—suspended particles in the submicrometre size range—are known to occur
naturally in ground water, and have the potential to enhance transport of non-soluble …

The recent estimated global stockpile of separated plutonium (Pu) worldwide is about 500 t,
with equal contributions from nuclear weapons and civilian nuclear energy. Independent of …

Highly parameterized and CPU‐intensive groundwater models are increasingly being used
to understand and predict flow and transport through aquifers. Despite their frequent use …

Concentrations of the rare earth elements (REE) were measured in circumneutral pH
groundwaters from southern Nevada and Death Valley, CA. Groundwaters from the regional …

Desert springs, often the sole sources of water for wildlife and cattle, support wetland and
wetland/upland transition ecosystems including rare and endemic species. In the basin and …

To improve our understanding and guide future studies and applications, we review the
biogeochemistry of the rare earth elements (REE). The REEs, which form a chemically …

The rare earth element (REE) signature of ground waters from both felsic volcanic rocks on
the Nevada Test Site and from the regional Paleozoic carbonate aquifer of southern Nevada …

A new δ18O map of southern Nevada groundwater shows a systematic decrease in δ18O
of∼ 5‰ from 36° to 39° N latitude. The variation is consistent with higher‐latitude recharge …

Samples collected from springs and wells in southern Nevada were analyzed for major
solutes and trace elements as part of a larger study to characterize the geochemical …

An inventory of long-lived radionuclides produced by 828 underground nuclear tests
conducted at the Nevada test site (NTS) from 1951 to 1992 includes residual tritium, fission …
