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

By SubcontractorHub Editorial Team·Published October 2026

Oxamyl in well water reviewed against the public 0.2 mg/L line

Quick Answer

Oxamyl in well water is read against a public MCLG of 0.2 mg/L and an MCL of 0.2 mg/L. The table also names it Vydate. The health cell says slight nervous system effects. The source cell names apples, potatoes, and tomatoes. A private well is not, by itself, the public-system rule.

An insecticide panel can list several names that share a runoff sentence, and the digit next to oxamyl is not unique. Dalapon prints the same 0.2 on both cells, with a kidney health cell and a rights-of-way herbicide source. 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.

Dalapon, at the same 0.2 mg/L, is the rights-of-way herbicide: dalapon in well water. Methoxychlor, at 0.04 mg/L, is a different insecticide row with a reproductive health cell: the national table says runoff or leaching from insecticide used on fruits, vegetables, alfalfa, and livestock. Lindane, at 0.0002 mg/L on both cells, names cattle, lumber, and gardens. Neither of those digits is 0.2.

The 0.2 Line Is Not Dalapon's 0.2

EPA's national primary table, fetched the day this page was written, lists oxamyl, also named Vydate, with an MCLG of 0.2 mg/L and an MCL of 0.2 mg/L. The potential-effects cell says slight nervous system effects. The source cell says runoff or leaching from insecticide used on apples, potatoes, and tomatoes. 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.

Dalapon prints 0.2 mg/L in both cells. Its health cell says minor kidney changes. Its source cell says runoff from herbicide used on rights of way. Sharing the digits is not sharing the chemical. An orchard-and-potato insecticide is not a rights-of-way herbicide. A nervous-system cell is not a kidney cell. Quoting a bare 0.2 without the name lets the next reader pick the herbicide row.

Methoxychlor, on that same table, prints 0.04 mg/L on both cells. Its health cell says reproductive difficulties. Its source cell says runoff or leaching from insecticide used on fruits, vegetables, alfalfa, and livestock. Sharing the word insecticide is not sharing the digit, and sharing the word fruits is not sharing apples, potatoes, and tomatoes as this row prints them. Lindane prints 0.0002 mg/L on both cells, with liver or kidney problems, and a source cell about cattle, lumber, and gardens. 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.

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 dalapon sentence, or methoxychlor's 0.04, from landing on a nervous-system row that said 0.2.

No Removal Percent Is Printed Here

The national page 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. The table prints the name Vydate next to oxamyl. Write the identifier the lab printed, and do not drop Vydate if the lab used it.

What Should the Oxamyl in Well Water Note Say?

Five lines keep the next visit from borrowing dalapon, or from writing a removal claim the table did not print. Name the contaminant the lab printed, show both cells, and keep the crop list attached.

  1. The contaminant name as the lab printed it, and not dalapon and not methoxychlor. If the lab says Vydate, keep that name next to oxamyl.
  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 oxamyl 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 dalapon's rights-of-way row.

Where the Row Sits on the Job

Oxamyl 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 pesticides skips the name and skips the fact that dalapon is a different source cell with the same digits.

The health cell on the fetched table is slight nervous system effects, 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 oxamyl. 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 dalapon's kidney row.

The crop list is specific. Apples, potatoes, and tomatoes are not the rights-of-way sentence, and they are not methoxychlor's longer list of fruits, vegetables, alfalfa, and livestock. If the lab names oxamyl, keep that crop list attached. Do not shorten it to "insecticide runoff" and let the next reader pick a 0.04 or a 0.0002 row.

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.

Frequently Asked Questions

What is the public oxamyl line?

The national primary table prints oxamyl, also named Vydate, with an MCLG of 0.2 mg/L and an MCL of 0.2 mg/L. The health cell says slight nervous system effects. The source cell says runoff or leaching from insecticide used on apples, potatoes, and tomatoes.

Is 0.2 mg/L the dalapon number?

The digits match dalapon's 0.2 mg/L on both cells of the same national table. Dalapon's health cell says minor kidney changes. Dalapon's source cell says runoff from herbicide used on rights of way. Oxamyl's source cell names an insecticide on apples, potatoes, and tomatoes. Same digits are not the same chemical.

Does this page print a removal percent?

No. The technology table was not fetched for this row on the day this page was written, so no carbon mark is printed here. A mark, when a page does print one, is not a removal percent.

Does this MCL apply to a single-home well?

The national page says these primary standards apply to public water systems. A single-home well is not named in that sentence. A state or county rule can still apply. Read the lab and the local rule.

Is this medical advice?

No. The health cell is the public table's potential-effects cell for long-term exposure above the MCL. It is not a finding about a person in the house.
