2,4-D (2,4-Dichlorophenoxyacetic Acid)

GENERAL INFORMATION
2,4-D is a colorless, odorless powder. 2,4-D is used as a herbicide for the control of broad-leaf weeds in agriculture, and for control of woody plants along roadsides, railways, and utilities rights of way. The major source of 2,4-D in drinking water is runoff from herbicide used on row crops.

HEALTH EFFECTS
Some people who drink water containing the weed killer 2,4-D well in excess of the MCL over many years could experience problems with their kidneys, liver, or adrenal glands.

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.
