Dalapon in Well Water: The Public 0.2 mg/L Line

By SubcontractorHub Editorial Team·Published October 2026

A herbicide panel can list several names that share a runoff sentence, and the digit next to dalapon is not the digit next to 2,4-D. The trap on this row is the opposite problem: oxamyl prints the same 0.2 on both cells. 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.

2,4-D, at 0.07 mg/L on both cells, is a row-crop herbicide with a longer health cell: 2,4-D in well water. Glyphosate, at 0.7 mg/L, is a different herbicide runoff sentence again: glyphosate in well water. Diquat, at 0.02 mg/L with a cataract cell, is not this 0.2: diquat in well water.

The 0.2 Line Is Not Oxamyl's 0.2

EPA's national primary table, fetched the day this page was written, lists dalapon with an MCLG of 0.2 mg/L and an MCL of 0.2 mg/L. The potential-effects cell says minor kidney changes. The source cell says runoff from herbicide used on rights of way. 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.

Oxamyl, also named Vydate on that table, prints 0.2 mg/L in both the goal cell and the MCL cell. Its health cell says slight nervous system effects. Its source cell says runoff or leaching from insecticide used on apples, potatoes, and tomatoes. Sharing the digits is not sharing the chemical. A rights-of-way herbicide is not an orchard insecticide. Quoting a bare 0.2 without the name lets the next reader pick the nervous-system row.

2,4-D, on that same table, prints 0.07 mg/L on both cells. Its health cell says kidney, liver, or adrenal gland problems. Its source cell says runoff from herbicide used on row crops. Sharing the word herbicide is not sharing the digit, and sharing the word kidney is not sharing the rest of the health cell. Dalapon's cell says minor kidney changes. It does not say liver, and it does not say adrenal gland. 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. Do not write the public MCL as if the well were a public system.

What the Dalapon 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 the oxamyl sentence, or 2,4-D's 0.07, from landing on a rights-of-way row that said 0.2.

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 Dalapon in Well Water Note Say?

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

1. The contaminant name as the lab printed it, and not oxamyl and not 2,4-D.
2. The result and the unit. If the unit is not milligrams per liter, do not drop the unit and call the result 0.2.
3. The public pair you compared it with: MCLG 0.2 mg/L and MCL 0.2 mg/L, named as the national dalapon 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 0.2 mg/L is oxamyl's insecticide row.

Where the Row Sits on the Job

Dalapon in well water 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 0.2 line into a carbon quote because the panel listed several herbicides skips the name and skips the fact that oxamyl is a different source cell.

The health cell on the fetched table is minor kidney changes, 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.

Both cells print 0.2 mg/L. That match is what the table printed. It is not a promise that the lab result was 0.2, and it is not a promise that a private well has no dalapon. Write both cells anyway. Dropping the goal because it matches the MCL is how a later reader treats 0.2 as if it were only an enforceable number with no goal, or as if it were oxamyl's nervous-system row.

A rights-of-way sentence is specific. It is not the row-crop sentence on 2,4-D, and it is not the shorter herbicide-use sentence on glyphosate. If the lab names dalapon, keep the rights-of-way source cell attached. Do not average it with a crop herbicide because both can show up on a long panel.

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.
