Chlordane, a synthetic organic chemical, is a viscous liquid, colorless to amber, with a slight chlorine-like aromatic odor. Chlordane was used in the past to kill a variety of insects. The only commercial use of chlordane products still permitted is for fire ant control in power transformers. Chlordane has been released into the environment primarily from its application as an insecticide. Chlordane may persist for long periods of time in air, soil and water.
Some people who drink water containing chlordane well in excess of the maximum contaminant level (MCL) for many years could experience liver or nervous system problems; increased risk of cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Chlordane levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Chlordane levels were detected in your water sample but do not exceed the maximum contaminant level.
