AAPG Bulletin (2021) 105 (1): 189–221.
... water samples were also analyzed for tritium ( 3 H), DIC (δ 13 C DIC ), 14 C, ratio of 129 I to 127 I ( 129 I/ 127 I), and microbial 16s ribosomal ribonucleic acid (rRNA) sequence. Among them, the water samples analyzed for δ 13 C DIC were prepared by injecting the water sample into evacuated septum...

... 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...

... for environmental isotope analyses ( Figure 5 ), and were sent to iThemba Labs in Gauteng, where they were analysed for stable isotope 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...
