..., September 2015, and July 2016 ( Fig. 1C ) and analyzed for their chemical composition, δ 2 H and δ 18 O values, and 3 H (bomb-tritium) activity (see the Data Repository for data and methods). The analyses of the warm springs were then corrected for mixing with modern surface waters (exemplified by the cold...

... 18 O and δ 2 H values ( ; ) of groundwater suggest that meteoric precipitation is the primary source with a small portion recharged during Pleistocene glaciation. Tritium (up to 17.42 TU) and coliform bacteria (up to 600 counts/100 ml) data indicate groundwater is generally recently recharged...

... compositions ( 18 O/ 16 O and 2 H/ 1 H) and Tritium ( 3 H) content. The equipment used for stable isotope analysis consisted of a Thermo Delta V mass spectrometer that was connected to a Gasbench, the former of which was able to separate atoms or rather ions with different mass and measure their relative...

... between pre-dam and post-dam river water occurs in samples from the aquifer beneath the Río Bravo floodplain, where finite tritium is also present. Along the flanks of the Sierra de Juárez, mixing occurs between pre-dam river water and water derived from the Sierra de Juárez. Carbon-14 content...

... the CT scans as the average CT number of the voxels in the grayscale image excluding macropores and stones. The CT matrix showed the best relationships with the solute transport characteristics, especially the time by which 5% of the applied mass of tritium was leached, known as the 5% arrival time ( t...

...S.R. Maples; B.J. Andraski; D.A. Stonestrom; C.A. Cooper; G. Pohll; R.L. Michel Abstract Effective isolation of tritium ( 3 H) and other contaminants at waste-burial facilities requires improved understanding of transport processes and pathways. Previous studies documented an anomalously widespread...

.... In general, the rate of gaseous carbon-14 release decreased with time. The results suggest a small initial release of relatively labile, accessible carbon-14, with longer term release occurring at a much slower rate. Tritium (T) releases were also measured. graphite carbon-14 tritium A t...
