This presentation shows maps of a very large plume of fugitive methane capture by Picarro in a drive-by emissions check in the town of Flower Mound 10 minutes from the Dallas-Fort Worth International Airport. The plumes were so elevated that the Picarro gas analyzer maxed out its readings -- likely environmental levels of fugitive methane were higher than in the chart. This may also imply extremely high levels of toxic VOCs such as benzene and xylene, both of which are often associated with methane in fugitive emissions resulting from petrochemical and natural gas installations. Alisa Rich of Wolf Eagle Environmental created this presentation using data gathered with a Picarro analzyer.
