2,4-D in Well Water: The Public 0.07 mg/L Line

By SubcontractorHub Editorial Team·Published October 2026

A herbicide panel can list several names that share a row-crop sentence. The digit next to 2,4-D is not the digit next to atrazine, and it is not safe to borrow because cis-1,2-dichloroethylene prints the same 0.07. Dealers who sell treatment still have to say which public line they are reading. SubcontractorHub is software for the customer record. This page is the row. It is not a treatment design, and it is not medical advice.

Atrazine, at 0.003 mg/L with a row-crop source cell, already has its own page: atrazine in well water. Glyphosate, at 0.7 mg/L, is glyphosate in well water. 2,4-D in well water is only this chemical. Moving the decimal from 0.07 to 0.7 is how a glyphosate sentence lands on the wrong row.

The 0.07 Line Is Not Atrazine's 0.003

EPA's national primary table, fetched the day this page was written, lists 2,4-D with an MCLG of 0.07 mg/L and an MCL of 0.07 mg/L. The potential-effects cell says kidney, liver, or adrenal gland problems. The source cell says runoff from herbicide used on row crops. Footnote 2 says units are milligrams per liter unless otherwise noted, and that milligrams per liter are equivalent to parts per million. This row did not opt out of that unit.

Atrazine, on that same table, prints 0.003 mg/L in both the goal cell and the MCL cell. Its health cell says cardiovascular system or reproductive problems. Its source cell also says runoff from herbicide used on row crops. Sharing the source sentence is not sharing the chemical. Quoting a bare row-crop phrase without the name lets the next reader pick atrazine's 0.003.

cis-1,2-Dichloroethylene, on that same table, prints 0.07 mg/L in both cells. Its health cell says liver problems. Its source cell says discharge from industrial chemical factories. Sharing the digits is not sharing the source. Glyphosate prints 0.7 mg/L, one decimal place away, with a source cell that says runoff from herbicide use. The opening sentence of the national page says these standards apply to public water systems. It does not name a single-home well. If the jug on the counter is a private well, say so.

What the 2,4-D in Well Water Note Holds

The table above is the note. It is not a quote, and it is not a removal design. A customer who wants a price still needs a test, a model, and a scope. Those live on the job. This page only stops atrazine's 0.003, or glyphosate's 0.7, from landing on a herbicide row that said 0.07.

No Removal Percent Is Printed Here

Footnote 1 says an MCL is set as close to the goal as feasible using the best available treatment technology and taking cost into consideration. That sentence is a definition of how an MCL is set. It is not a percent a cartridge will remove, and it is not a price. The technology table that marks carbon, aeration, or oxidation was not fetched for this row on this date, so this page does not invent an X.

How a mark on that table differs from a treatment technique is what best available technology means. If you sell carbon, say you sell carbon. Do not say a mark you did not fetch is a guarantee on this well. No removal percentage was fetched for this row, so none is printed here. No installed price was fetched, so none is printed. No CAS number was fetched for this row on this date, so none is printed. Write the identifier the lab printed.

What Should the 2,4-D in Well Water Note Say?

Five lines keep the next visit from borrowing atrazine, or from writing a removal claim the table did not print. Name the contaminant the lab printed, show both the goal and the MCL, and say whether the jug is a private well.

1. The contaminant name as the lab printed it, and not atrazine and not glyphosate.
2. The result and the unit. If the unit is not milligrams per liter, do not drop the unit and call the result 0.07.
3. The public pair you compared it with: MCLG 0.07 mg/L and MCL 0.07 mg/L, named as the national 2,4-D row.
4. Whether the sample is a private well or a public system. The national page names public water systems. It does not name a single house.
5. What you did not claim: no removal percent, no installed price, no CAS, and no statement that 0.07 mg/L is cis-1,2-dichloroethylene's factory row.

Where the Row Sits on the Job

The lab sheet belongs with the customer, the address, and the date of the sample. A price for equipment is a later page, after someone has read this row and the rows next to it. Mixing the 0.07 line into a softener quote because the panel listed several herbicides skips the name and skips the fact that atrazine is a different digit.

A row-crop source sentence is shared by more than one herbicide. Write the name before you write the sentence. If the lab header says 2,4-D, the public pair is 0.07 mg/L and 0.07 mg/L. If the header says atrazine, the public pair is 0.003 mg/L and 0.003 mg/L. If the header says glyphosate, the public pair is 0.7 mg/L and 0.7 mg/L. The shared words about runoff do not give you permission to move the decimal.

The health cell on the fetched table is kidney, liver, or adrenal gland problems, described as a potential effect of long-term exposure above the MCL. That sentence is the public table's cell. It is not a finding about the household, and it is not a reason to add a medical claim the lab did not print. If a customer asks what the number means for a person, the honest line is that this page is not medical advice.

Simazine, at 0.004 mg/L with a herbicide-runoff source cell, is another neighbor that is not this row: simazine in well water. Chlordane, at an MCL of 0.002 mg/L with a banned-termiticide source cell, is not a row-crop herbicide either.

How a dealer reads a full panel, including which tests were actually run, is the well water testing guide. The difference between a goal and an enforceable level is MCL and MCLG. The software that holds the customer file is water treatment contractor software. This article does not size a filter and does not tell a household the water is safe to drink.
