A wall of foam appeared on a canal following firefighting efforts at the Carbogen Amcis chemical plant in Clayton, England, according to an article from ABC News. The foam started appearing in the nearby waterway after fire crews used a variety of water jets to battle the blaze.
Initial water quality testing indicates no adverse effects on the canal and no impact on the fish, according to the article. The Greater Manchester Fire and Rescue Authority does not believe the firefighting materials were the cause of the foam. In the U.S., however, a fire-suppressing material known as aqueous film-forming foam (AFFF) is used by the Navy to extinguish hydrocarbon fuel fires, notes ABC News.
