The Ankeny, Iowa wastewater treatment facility (WWTF) was decommissioned in November 2013 providing a unique opportunity to characterize the impacts of WWTF discharge on water quality at the surface-water/groundwater interface in a shallow, unconfined alluvial aquifer. The Ankeny WWTF discharged treated effluent for nearly forty years into Fourmile Creek, located in Ankeny, Iowa. Dataset includes site information (Table 1), analytical methods (Table 2), piezometer water level elevations (Table 3), trace and major element concentrations collected from 2011 to 2013 before the WWTF shutdown (Table 4), and trace and major element concentration collected from 2013 to 2014 after the WWTF shutdown (Table 5).

Central Asia, site of the historic Silk Road trade network, has long been a conduit for the movement of people, energy, and mineral resources between Europe and Asia. Once part of the former Soviet Union, this region was and continues to be an important producer of base and precious metals, rare metals (RM), including niobium, tantalum, and beryllium, and a past producer of rare earth elements (REE). The Tien Shan and Pamir Mountains regions, encompassing parts of Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, and Turkmenistan, are of significant interest for mineral exploration as these regions are thought to host substantial undeveloped and undiscovered resources of REE and RM. Based on this legacy, and as an...

This data set compiles the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) at Bokan Mountain, located in the southern part of Prince of Wales Island, southeastern Alaska. Bokan Mountain was formed by an Early Jurassic peralkaline igneous complex that intruded into lower Paleozoic rocks of the Alexander terrane of southeast Alaska. The pluton and surrounding country rocks host numerous mineral deposits and occurrences, including heavy rare earth element (HREE)-rich pegmatites and felsic dikes, as well as mineral deposits rich in uranium, thorium, HREE, and fluorine. The Ross-Adams mine on Bokan Mountain exploited a uranium-thorium deposit intermittently from the late...
