Endothall is an organic solid of white odorless crystals. Endothall is used as a defoliant for a wide range of crops and as a herbicide for both terrestrial and aquatic weeds. It is used as a desiccant on lucerne and on potato, for the defoliation of cotton, to control aquatic weeds and as an aquatic algicide growth regulator. It has been used for sugar beets, turf, hops sucker suppression; alfalfa, clover desiccants; potato vine killers. The major source of endothall in drinking water is runoff from herbicide use.
Some people who drink water containing endothall well in excess of the maximum contaminant level (MCL) for many years could experience problems with the stomach or intestines.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Endothall levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Endothall levels were detected in your water sample but do not exceed the maximum contaminant level.
