Methane-Oxidizing Bacteria Communities Shift to Attenuate a Controlled Vadose Zone Methane Release

Autor: Mark L. Felice, Radomir Schmidt, Juan Peng, Nicholas R. de Sieyes, Kate M. Scow, Douglas M. Mackay

Publikováno v: Vadose Zone Journal, Vol 17, Iss 1 (2018)

Methane generated from small-rate releases of ethanol-blended fuels into the vadose zone potentially poses health and safety risks. Ubiquitous methane-oxidizing bacteria (MOB) in soils can convert CH into CO, potentially alleviating these risks. Unde

Methods to Estimate Source Zone Depletion of Fuel Releases by Groundwater Flow

Autor: Timothy E. Buscheck, Douglas M. Mackay, Eric J. Daniels, Nicholas R. de Sieyes, Juan Peng, Emily Hathaway, Radomir Schmidt, Charles J. Paradis, Ehsan Rasa

Publikováno v: Groundwater Monitoring & Remediation. 38:26-41

We compare two methods for estimating the natural source zone depletion (NSZD) rate at fuel release sites that occurs by groundwater flow through the source zone due to dissolution and transport of biodegradation products. Dissolution is addressed id

Autor: Maya C. Buelow, Sanjai J. Parikh, Fungai N.D. Mukome, Joseph J. Pignatello, Juan Peng, Thomas P. Hoelen, Douglas M. Mackay, Natasha Sihota, Junteng Shang, Michael J. Rodriguez

Publikováno v: Environmental Pollution. 265:115006

The impact of organic bulking agents on the biodegradation of petroleum hydrocarbons in crude oil impacted soils was evaluated in batch laboratory experiments. Crude oil impacted soils from three separate locations were amended with fertilizer and bu

Effect of different transport observations on inverse modeling results: case study of a long-term groundwater tracer test monitored at high resolution

Autor: Kate M. Scow, Laura Foglia, Ehsan Rasa, Douglas M. Mackay

Publikováno v: Hydrogeology journal, vol 21, iss 7

Conservative tracer experiments can provide information useful for characterizing various subsurface transport properties. This study examines the effectiveness of three different types of transport observations for sensitivity analysis and parameter
