New Equilibrator Design for Rapid Detection of Methane in Groundwater During Purging

Rapid Advances in Mobile Mass Spectrometry Enhance Tracer Hydrology and Water Management

“…Mobile MS systems have also been applied to monitor gas transport during controlled injections into aquifers (Cahill et al, 2020;Chatton et al, 2017;Chopra, 2020;Soares, 2020). Similarly, real-time measurements of methane concentrations in groundwater can help to monitor natural gas development (Ruybal et al, 2018) and to distinguish natural from anthropogenic methane sources in groundwater (Darrah et al, 2014(Darrah et al, , 2015; used grab samples). In the field of carbon capture and storage, real-time measurements of noble gases can be used to monitor the effectiveness of carbon removal processes (Sundal et al, 2019) and serve as an early warning sign for CO 2 leakage from storage facilities, as demonstrated in laboratory experiments (Kilgallon et al, 2018).…”
