Endothall

GENERAL INFORMATION
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.

HEALTH EFFECTS
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.

Treatment options: 

TREATMENT OPTIONS
Granular Activated Carbon (GAC) or Powdered Activated Carbon (PAC) are considered the best available technologies (BAT) for treatment of many organic contaminants including organic pesticides, volatile organic compound (VOCs), and Trihalomethanes (THMs) (by-products of chlorination). Treatment can be at the tap (called point of use or POU) or the entire house.
