Penn State Extension will host a webinar on March 14 starting at 1:00 on a case study of methane migration and changes in aquifer properties.

Josh Woda, a Penn State Department of Geosciences graduate student, will explain how methane migration can change aquifer properties as well as what we can learn by investigating case studies near hydrocarbon migration.

The origin of methane migration into water resources has been an area of concern in areas of shale development. Pennsylvania does not regulate private homeowner water wells on top of the naturally occurring methane.

Detection of a methane leakage source can be difficult to determine. Recent Penn State research has found new tracers that can help determine impacts from recent gas migration.

“Very little is understood about how methane migrates in the subsurface and what geochemical changes it can induce along its flow path,” Woda stated. “We studied an area containing elevated methane for over seven years to understand observations related to and the plausible causes of methane migration. Observed changes in metal concentrations and sulfate depletion at the study site might allow better prediction of what happens in the subsurface at other locations when methane is introduced, as well as revealing whether methane is natural or anthropogenic in origin.”
