A xylene is any of a group of very similar organic compounds. They are clear liquids with a sweet odor. The greatest use of xylenes is as a solvent which is much safer than benzene. Other uses include: in gasoline as part of the BTX component (benzene-toluene-xylene); Xylene mixtures are used to make phthalate plasticizers, polyester fiber, film and fabricated items. The major sources of xylenes in drinking water are discharge from petroleum factories; and discharge from chemical factories.
Some people who drink water containing xylenes well in excess of the maximum contaminant level (MCL) for many years could experience damage to their nervous system.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Xylene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Xylene levels were detected in your water sample but do not exceed the maximum contaminant level.
