Cyanide is a carbon-nitrogen chemical unit which combines with many organic and inorganic compounds. The most commonly used form, hydrogen cyanide, is mainly used to make compounds and other synthetic fibers and resins. The major source of cyanide in drinking water is discharge from industrial chemical factories.
Some people who drink water containing cyanide well in excess of the maximum contaminant level (MCL) for many years could experience nerve damage or problems with their thyroid.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Cyanide levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Cyanide levels were detected in your water sample but do not exceed the maximum contaminant level.
