Abstract
Devices and methods for directing a non-aqueous phase liquid (NAPL) that migrate entrained in a fluid (e.g., a gas) from sediments in bodies of water by using trapping caps having an upwardly sloped surface toward an accumulation zone that contains a water table, in which migration of the gas carries the NAPL toward the accumulation zone.
