Effect of salt on aerobic biodegradation of petroleum hydrocarbons in contaminated groundwater.
Ania C. Ulrich,Selma E. Guigard,Julia M. Foght,Kathleen M. Semple,Kathryn Pooley,James E. Armstrong,Kevin W. Biggar +6 more
TL;DR: Of particular interest is the observation that low concentrations of salt (≤1% NaCl) slightly stimulated mineralization in some cases.

Microbial reduction of sulfate injected to gas condensate plumes in cold groundwater.
TL;DR: Sulfate was injected into groundwater contaminated by gas condensate plumes at two petroleum sites in Alberta, Canada to enhance in-situ bioremediation, and conservative estimates for sulfate reduction rates yielded conservative estimates.

A socio-ecological adaptive approach to contaminated mega-site management: From 'control and correct' to 'coping with change'
TL;DR: It is contended that the best that can be hoped for in mega-site management is an acceptable solution for the current state of affairs, with good flexibility to modify strategies as new site conditions, remediation possibilities, community preferences and management objectives develop over time.

Intrinsic bioremediation of diesel-contaminated cold groundwater in bedrock
Katharine M Cross,Kevin W. Biggar,Kathy Semple,Julia M. Foght,Selma E. Guigard,James E. Armstrong +5 more
TL;DR: In this paper, a diesel fuel migrated from a well lease site into underlying fractured bedrock contaminating the groundwater-bearing zone approximately 30 m below ground surface and was analyzed to evaluate natural attenuation, specifically intrinsic bioremediation.

Cores of aquitard sediment yield details about natural attenuation in gas condensate-contaminated groundwater.
TL;DR: In this article, the authors demonstrated that microbial sulfate reduction has been a dominant process associated with natural attenuation of hydrocarbons in the saturated zone of the vadose zone and shallow groundwater in an aquitard.
