Abstract
Geochemical and microbiological indicators of methane (CH4) production,
oxidation and migration processes in groundwater are important to understand
when attributing sources of gas. The processes controlling the natural
occurrence of CH4 in groundwater must be understood, especially when
considering the potential impacts of the global expansion of coal seam gas
(CSG) production on groundwater quality and quantity. We use geochemical and
microbiological data, along with measurements of CH4 isotopic
composition (δ13C-CH4), to determine the processes acting upon
CH4 in a freshwater alluvial aquifer that directly overlies coal
measures targeted for CSG production in Australia. Measurements of CH4
indicate that there is biogenic CH4 in the aquifer; however, microbial
data indicate that there are no methanogenic archaea in the groundwater. In
addition, geochemical data, particularly the isotopes of dissolved inorganic
carbon (DIC) and dissolved organic carbon (DOC), as well as the concentration
of SO42−, indicate limited potential for methanogenesis in situ.
Microbial community analysis also shows that aerobic oxidation of CH4
occurs in the alluvial aquifer. The combination of microbiological and
geochemical indicators suggests that the most likely source of CH4,
where it was present in the freshwater aquifer, is the upward migration of
CH4 from the underlying coal measures.
