Rice study: higher ethanol blends require different approach to deal with vapor intrusion in buildings; extreme event, low probability

Green Car Congress

A study lead by researchers at Rice University suggests that current approaches to manage the vapor intrusion risk into buildings in the vicinity of conventional fuel spills might need to be modified when dealing with some higher ethanol blend fuel (i.e., E20 up to E95) releases. Pedro Alvarez, corresponding author. Rixey, and Pedro J.
