AAPG Bulletin (2021) 105 (1): 189–221.
..., the shallow CBM samples from these two regions all show evident PMG characteristics (AF or CR) or biological degradation, which may be related to an active hydrodynamic field and low TDS values ( Fu et al., 2019 ). In addition, the partial CBM-coproduced water samples were also analyzed for tritium ( 3 H...

... 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...
