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.
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.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
2,4-D levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
2,4-D levels were detected in your water sample but do not exceed the maximum contaminant level.
