Enviroforensics’ President & CEO, Stephen Henshaw talks commingled plumes. When contaminated groundwater plumes run together, who is responsible for the clean up?
A commingled plume is the term used when two or more plumes of contaminated groundwater blend together. The blending or commingling of groundwater plumes is a fairly common occurrence in urban or commercial settings. A very common illustration of commingled plumes is when the groundwater beneath two corner gas stations is contaminated with releases from the underground storage tanks. The groundwater may all move in the same general direction, but because the plumes spread or fan out as they migrate, the plumes blend together and overlap one another.
