2,4-Dichlorophenoxyacetic Acid or 2,4-D is colorless and odorless and has been typically used as a herbicide for the control of broadleaf weeds and brush in agricultural areas (row crops/ rice), industrial areas, turf and landscape areas, control of woody plants along roadsides, railways, utility right of way, and in aquatic habitats. In an aerobic (high oxygen) environment, 2,4-D has a biologic half-life of about 14 days, but butoxyethyl ester (Triclopyr), a form of 2,4-D, has a half-life of 3 to over 314 days in soil (30 day average) and in water without sunlight up to 142 days (Source).
2,4-D was one of the components of Agent Orange and is an auxin-type herbicide that causes the plant to attempt to continuously grow and divide. The auxin induces the production of the plant hormone ethylene which can inhibit elongation growth that causes the leaves to fall off the plant, resulting in a plant that will ultimately die.
For humans, 2,4-D is not readily absorbed by the skin or lungs, but dermal contact with the concentrated chemical has been associated with skin irritation irrigation. When the chemical is ingested in a diluted form, it is most likely distributed throughout the body via the bloodstream but does not build up in any tissues. When 2,4-D is in the body it can impact the thyroid, adrenal gland, kidneys, and fetal development (Source). About 75% of the 2,4-D that is consumed is flushed from the human body, primarily via urination, in about 4 days.
People who consumed products containing 2,4-D may vomit, have diarrhea, headaches, and become confused or aggressive. Some people with long-term low-dose exposure had kidney failure and skeletal muscle damage. Long-term exposure can result in damage to the liver, kidneys, and endocrine glands in humans.
2,4-D is regulated as a primary drinking water standard and both the MCL and MCLG are set at 0.07 mg/L. The DWEL is 0.2 mg/L. It is not classified as a human carcinogen. Hong Kong and the WHO have a drinking water standard of 0.03 mg/L.
One-Day HA: The concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects for up to one day of exposure. The One-Day HA intended to protect a 10-kg child consuming 1 liter of water per day is 1 mg/L.
Ten-Day HA: The concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects for up to ten days of exposure. The Ten-Day HA intended to protect a 10-kg child consuming 1 liter of water per day is 0.3 mg/L.
When 2,4-D decomposes, it produces 2,4-dichlorophenol which is not regulated as a primary drinking water standard but does have a DWEL of 0.1 mg/L and a Life-Time health advisory concentration of 0.02 mg/L. The life-time health advisory is the concentration of a chemical in drinking water that is not expected to cause any adverse noncarcinogenic effects over a lifetime of exposure.
If you get your water from a public water supply system it is not likely the water contains 2,4-D at or above the primary drinking water standard, but it may be detectable. You are likely at greater risk to exposure from 2,4-D, if you have a private well, consume water from a transient non-community system, or get your water from a spring or other surface water source. Also, if you are located in an area with a historic high usage or storage of 2,4-D, near a manufacturer of 2,4-D, near a lake treated with 2,4-D, and/or located near an active or abandoned landfill, you may have a problem.
Level 1 Testing is done with simple observations that an individual can make with their own senses such as sight, smell, and taste. These observations can be readily apparent or can be observed as they change over time. In addition, accessible related information about the home can also be used to narrow down the cause of your water issues.
The taste and odor threshold for 2,4-D is 3.13 mg/L, however when 2,4-D decomposes to 2,4-dichlorophenol, it has an odor threshold of 0.0003 mg/L. (Source) The odor has been described as "medicinal". If you are on city water, what does your Annual Consumer Confidence Report say?
There are not many self-testing tools or warning signs to help identify this problem, but it appears that the water may have a slight odor. The better tool would be to understand your source and your location, location, location, and the known surrounding hazards or activities that can be associated with this chemical.
2,4-D is not a common problem for a regulated water system like a city water source. There is a great concern for private water sources that are located in an area where the chemical was manufactured, stored, or used. If you are in one of the targeted areas mentioned, concerned about a past use, or your source is positive for bacterial contamination, with or without an elevated level of nitrate or nitrite, and appears to have been a change in water quality after a major recharge or storm event, you may want to screen your water for 2,4-D.
Level 2 Testing is Do-It-Yourself testing that can be done in your own home using a Testing Kit. After you’ve done Level 1 Testing, Level 2 Testing can confirm if your observations are correct. If your test results reveal the presence of a contaminant that is cause for concern, you can either proceed to determine the best treatment (see below) or continue to Level 3 Testing.
We are not aware of a low-cost screening test to check your water or air for 2,4-D, but there are some general screening kits for the presence of pesticides and 2,4-D can be commonly used in combination with Roundup or glyphosate. It is likely that these pesticide screening tests check for "atrazine and simazine" as a general surrogate for all pesticides and not specifically for 2,4-D or glyphosate.

Level 3 Testing is done through an accredited Water Testing Laboratory. With Level 3 Testing, you can order a testing kit that is used to prepare your sample and submit it to the lab. By utilizing a lab, you have the assurance that a certified water expert had analyzed your water sample. If your test results reveal the presence of a contaminant that is cause for concern, you can either proceed to determine the best treatment options (see below) or continue to Level 4 Testing - Certified Testing.
Not all informational water quality tests include 2,4-D and other pesticides and herbicides. The following are informational water quality tests that include testing for this and similar compounds. If you have not done a comprehensive evaluation of your drinking water, we recommend the National Testing Labs City Water or Water Check Deluxe testing packages.

A Level 4 Certified Test Test uses chain-of-custody with a water professional coming to your home to prepare the water sample and then works with an accredited laboratory in order to certify your test results. This type of testing not only gives you the highest level of assurance in the accuracy of your test results, but can also be used as a document in legal cases. For Baseline Testing, we recommend that you use Certified Testing.
If you need certified testing for 2,4-D, we advise testing for a broader range of herbicides and pesticides, nutrients, and other contaminants that are likely associated with the source of the contamination. If you do not know the source of the contamination and nature of the contaminant, we strongly recommend conducting informational water testing first to characterize the general water quality and testing for a broad range of chemical compounds. If you need help with developing a screening program or finding a certified laboratory, please contact our team.
Order a Neighborhood Environmental Report to learn about potential hazards in your community.
It is unlikely that there will be significant problems with 2,4-D in a public water supply system, but it is more likely this problem would be associated with a transient non-community system or a private system or a source that is directly down-gradient from an industrial use, landfill, agricultural area, or possibly a lake community using a lake treatment that includes 2,4-D. The primary treatment system that can remove 2,4-D is a granular-activated-carbon filtration system.
2,4-D is low in toxicity if eaten, inhaled, or if it contacts the skin, and some forms are low in toxicity to the eyes. However, the acid and salt forms of 2,4- D can cause severe eye irritation (Source). Based on this information, the primary recommendation is to either use an alternative water source or a bottled water source for consumption and consider adding an in-line or point-of-use carbon block or granular Carbon Filtration units on drinking water fixtures, bathing facilities, and shower heads.

Granular-activated-carbon filtration systems have been shown to be effective against 2,4-D, but since other organics, chlorine, particles, and other compounds will react with the granular-activated-carbon (use up its capacity), it is necessary to conduct a detailed biological and chemical analysis of the water and to develop a suitable treatment train that will ensure that your water is potable, i.e., drinkable. The best way to develop a long-term solution is to have a comprehensive water quality test and work with a water quality professional.
