Groundwater Monitoring & Remediation [Published online 7 June 2020 prior to print]
Oxygen influx (measured by the gradient method), long-term carbon dioxide efflux (measured with carbon traps), instantaneous carbon dioxide efflux (measured with dynamic closed chambers), and the heat flux from biodegradation (measured by thermal natural source zone depletion [NSZD] monitoring), were used to measure NSZD of LNAPL at a site in Southern California. The NSZD rates were compared, and their sources of variability, the extent NSZD processes occur in LNAPL within the saturated zone, and how NSZD is related to LNAPL composition change over time were evaluated.
