Distribution of ETBE-degrading microorganisms and functional capability in groundwater, and implications for characterising aquifer ETBE biodegradation potential

Aug 4, 2021

Microbes in aquifers are present suspended in groundwater or attached to the aquifer sediment. Groundwater is often sampled at gasoline ether oxygenate (GEO)-impacted sites to assess the potential biodegradation of organic constituents. However, the distribution of...

A comparison of three methods to assess natural source zone depletion at paved fuel retail sites

Jun 28, 2021

Natural source zone depletion (NSZD) encompasses all processes that result in petroleum hydrocarbon light non-aqueous phase liquid (LNAPL) mass loss. Vertical gas transport between the subsurface and atmosphere is a key component of NSZD. Gas exchange with the...

Effect of environmental conditions and microbial communities on ETBE biodegradation potential in groundwater

Sep 18, 2020

Report no. 19/20: This report describes research carried out to determine: a) the environmental conditions which may support Ethyl tert butyl ether (ETBE) biodegradation in groundwater, b) the prevalence of ETBE biodegradation potential at ETBE-release sites (mainly)...

Biodegradation and fate of ethyl tert-butyl ether (ETBE) in soil and groundwater: A review

Mar 4, 2020

This review summarises the current state of knowledge on the biodegradation and fate of the gasoline ether oxygenate ethyl tert-butyl ether (ETBE) in soil and groundwater. Microorganisms have been identified in soil and groundwater with the ability to degrade ETBE...

Influence of contaminant exposure on the development of aerobic ETBE biodegradation potential in microbial communities from a gasoline-impacted aquifer

Jan 3, 2020

Aerobic biodegradation of ethyl tert butyl ether (ETBE) in a gasoline-impacted aquifer was investigated in laboratory microcosms containing groundwater and aquifer material from ETBE-impacted and non-impacted locations amended with either ETBE, or ETBE plus methyl...
