Contaminant Level (MCL)
Xylenes are a group of similar organic compounds used in pharmaceuticals, as insecticides, in detergents and as solvents for paint, adhesives and inks. They are also used in the blending of gasoline and airplane fuel.
Xylenes can arrive in water as discharge from chemical and petroleum factories.
Some people who drink water containing xylenes well in excess of the maximum contaminant level [10 milligrams per Liter ] for many years could experience damage to their nervous system.
The EPA recommends granular activated carbon (GAC) combined with packed tower aeration (an air stripping technique) for the treatment of xylenes. Lynntech reports that activated carbon has a “very high probability” of removing xylene on its own.Sources: EPA, WHO, IARC, Lynntech, Photo: WikiMedia, author: Secl
