“…3). The Eu anomaly is relatively common in southern Nevada groundwater and reflects the pattern observed for the volcanic rocks of the region (Johannesson et al 2000). Pinpointing the origin of the negative Ce anomaly in groundwater samples near Yucca Mountain is more complex.…”

“…Pinpointing the origin of the negative Ce anomaly in groundwater samples near Yucca Mountain is more complex. A negative Ce anomaly is observed for the carbonate rocks of the region, possibly reflecting the seawater from which they precipitated (Johannesson et al 2000). The presence of this anomaly in relatively shallow volcanic rock aquifers has caused researchers to suggest upwelling of groundwater from deep carbonate aquifers into the more shallow alluvial groundwater systems (Stetzenbach et al 2001).…”

“…Finally, oxidation and removal of Ce from solution as the water travels through the vadose zone is another possibility that cannot be eliminated (Leybourne et al 2000). It is worth noting that Hanson (1980), whereas the NTS volcanic rock normalizing factor is the mean value for each rare earth element for six different felsic volcanic rocks collected from the Nevada test site and present in Table 2 of Johannesson et al (2000). The numbers provided in the legend are for individual sample identification.…”

“…The numbers provided in the legend are for individual sample identification. The mean is for the five samples listed because negative Ce anomalies are not usually observed for groundwater from perched felsic volcanic-rocks from the Nevada test (Johannesson et al 2000) the seepage studied probably comes from recent infiltration rather than older perched water that was induced to flow.…”

Yucca Mountain is being considered as a geological repository for the USA's spent nuclear fuel and high-level nuclear waste. Numerous groundwater seeps appeared during March 2005 within the exploratory studies facility (ESF), a tunnel excavated in the mountain. Because of the relevance to radionuclide transport and unsaturated zone-modeling studies, we analyzed the seep samples for major anions and cations, rare earth elements, and colloids. Major ion species and elemental concentrations in seep samples reflect interaction of the water with the volcanic rock and secondary calcites. Elemental fractograms from flow-injection field-flow fractionation ICP-MS scans detected Br, Ca, Cl, Cu, Fe, I, Mg, Si, Sr, W, and U at void fractions, suggesting they may be present in the form of dissolved anions. Colloids approximately 10 nm in hydrodynamic diameter, possibly calcite, were also present in the seepage samples. Geochemical calculations indicate, however, these may be an artifact (not present in the groundwater) which arose because of loss of CO2 during sample collection and storage.

“…Numerous studies have already been done with respect to REEs in water systems, especially in relation to geochemistry (Dobson et al 2001;Hermann 2002;Vital and Stattegger 2000). During the past decades, REEs have been investigated in seawater (Elderfield et al 1990;Sholkovitz et al 1994), groundwater (Janssen and Verweij 2003;Johannesson et al 1996Johannesson et al , 1999Johannesson et al , 2000Smedley 1991), stream waters (Elderfield et al 1990;Gaillardet et al 1997;Hoyle et al 1984;Ingri et al 2000a;Sholkovitz 1992Sholkovitz , 1995, and lakes (Gammons et al 2003;Lyons 1994, 1995;Zhu et al 2005). In China, the abundance of REEs in the soil were measured in the 1980s (Wei et al 1990; Wei and Liu 1991).…”

This paper analyses the contents and species distributions of rare earth elements (REEs) in the water-suspended particulate-sediment system of the Baotou section of the Yellow River, China, with known anthropogenic REE input from industrial discharges. The major forms of REEs were suspended and dissolved in the mainstream and the tributaries of the Baotou section, respectively. The concentrations of the dissolved and suspended REEs had the same trends in the overlying water along the mainstream, which increased from the Seqi section (site A) to the mouth of the Sidaosha River (site D), reaching a maximum value at site D, and tending to decrease thereafter. The contents of REEs in sediment cores showed enrichment with light rare earth elements (LREEs). The bound to carbonates and to Fe-Mn oxides are the major forms of REE in the secondary phase and the REE exhibited LREE enrichment pattern and moderate Eu depletion in suspended particulates and surface sediments. The contents and species distributions of REEs in the water-suspended particulate-sediment system of the Baotou section suggest that the anthropogenic source of REEs from Baotou city have enhanced REE accumulation to the Baotou section. This information is important for predicting possible pollution resulting from anthropogenic REE input into rivers.

According to spider patterns five different types of thermal groundwater are distinguishable in Jordan. Each spider diagram comprises groups of elements which characterise soluble minerals of the aquifer such as halite, calcite, and gypsum, and leachable fractions of trace elements such as B, Ba, Br, Y, Cs, Rb, and U. In Jordan, mineralization of groundwater is largely controlled by dissolution of halite, carbonates, gypsum, and leaching diverse K-bearing minerals. Caused by interaction with Neogene basalts, limestones are silicified and mineralogically altered. Groundwater from these aquifers significantly differs in composition from those of the unaltered limestone aquifers. The benefit of spider patterns is that they visualise (i) chemical differences in groundwater from essentially similar aquifer rock such as young, old or thermally altered limestones and (ii) chemical similarities of groundwater produced from different geological formations. In contrast to spider patterns, ionic ratios widely overlap and do not unequivocally allow grouping of groundwater.
