Endrin is an organic solid of odorless white crystals. Endrin is an insecticide which has been used mainly on field crops such as cotton, maize, sugarcane, rice, cereals, ornamentals, and other crops. It has also been used for grasshoppers in non-cropland and to control voles and mice in orchards. Once widely used in the United States, most uses were cancelled in 1980. The major source of endrin in drinking water is residue of banned insecticide.
Some people who drink water containing endrin well in excess of the maximum contaminant level (MCL) for many years could experience liver problems.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Endrin levels were detected in your water sample to exceed the maximum contaminant level (MCL).
