Trihalomethane occur when naturally-occurring organic and inorganic materials in the water react with the disinfectants, chlorine and chloramine.
Some people who drink water containing total trihalomethanes in excess of the MCL over many years could experience liver, kidney, or central nervous system problems and increased risk of cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Trihalomethane levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Trihalomethane levels were detected in your water sample but do not exceed the maximum contaminant level.
