Toxaphene in Well Water: The Public 0.003 mg/L Line

By SubcontractorHub Editorial Team·Published November 2026

A pesticide panel can list several insecticide names on one page. The digit next to toxaphene is not safe to borrow just because lindane also names cattle, and it is not the matched 0.05 next to Silvex. 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.

The 0.003 Line Sits Under a Zero Goal

EPA's national primary table, fetched the day this page was written, lists toxaphene with an MCLG of zero and an MCL of 0.003 mg/L. The potential-effects cell says kidney, liver, or thyroid problems and an increased risk of cancer. The column header calls that a potential health effect from long-term exposure above the MCL, unless a row is specified as short-term. This row is not marked short-term. The source cell says runoff or leaching from insecticide used on cotton and cattle. 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.

The goal is zero and the MCL is not. That is the point that gets lost when a neighbor's matched pair is pasted onto this name. 2,4,5-TP, also called Silvex on the table, prints 0.05 mg/L in both cells. Its health cell says liver problems. Its source cell says residue of a banned herbicide. Sharing a place near toxaphene on the organic list is not sharing the goal, and an insecticide used on cotton and cattle is not a banned herbicide.

Lindane, on that same table, prints 0.0002 mg/L in both cells. Its health cell says liver or kidney problems. Its source cell says runoff or leaching from insecticide used on cattle, lumber, and gardens. Cattle appears in both source cells. That shared word is not a shared digit, and lindane's goal is 0.0002, not zero. A matched fumigant row at 0.04 mg/L is carbofuran in well water. The opening sentence of the national page says these standards apply to public water systems. It does not name a single-home well.

What the Toxaphene in Well Water Note Holds

The goal cell is zero. The page defines an MCLG as the level of a contaminant in drinking water below which there is no known or expected risk to health. It says MCLGs allow for a margin of safety and are non-enforceable public health goals. A zero goal is not a lab result of zero, and it is not a statement that the well has no toxaphene.

The MCL cell is 0.003 mg/L. The page defines an MCL as the highest level of a contaminant that is allowed in drinking water. It says MCLs are set as close to MCLGs as feasible using the best available treatment technology and taking cost into consideration, and that MCLs are enforceable standards. That definition is the public rule's definition. It is not a price for a filter, and it is not a percent removed.

The health cell names the kidney, the liver, or the thyroid, and an increased risk of cancer. That sentence is the public table's cell. It is not a finding about a person in the house. If a customer asks what the number means for a person, the honest line is that this page is not medical advice. Do not shorten it to liver problems because Silvex stops there. This row also names the kidney and the thyroid, and it names cancer.

The source cell is runoff or leaching from insecticide used on cotton and cattle. Keep both crops and animals on the note. Do not shorten it to "insecticide" and let the next reader pick lindane's lumber and gardens. The difference between a goal and an enforceable level is MCL and MCLG. On this row they do not match. On Silvex they do.

No Removal Percent Is Printed Here

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 lindane's 0.0002, or Silvex's 0.05, from landing on an insecticide row whose goal is zero and whose MCL is 0.003.

Best available technology, when a page names a mark, is explained in what is best available technology. No mark was fetched for toxaphene on this date, so none is printed. A carbon sentence copied from a neighbor is not this row. A zero-goal termiticide row at 0.0004 mg/L is heptachlor in well water. That page already warns not to borrow a neighbor's digit. The same warning applies here. Cotton and cattle are not a termiticide.

What Should the Toxaphene in Well Water Note Say?

Five lines keep the public pair from being rewritten as a private-well fine or as lindane.

1. The contaminant name as the lab printed it, and not lindane and not Silvex and not heptachlor.
2. The result and the unit. If the unit is not milligrams per liter, do not drop the unit and call the result 0.003.
3. The public pair you compared it with: MCLG zero and MCL 0.003 mg/L, named as the national toxaphene 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 zero means the sample was clean or that 0.003 mg/L is lindane's 0.0002.

Where the Row Sits on the Job

Toxaphene 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 0.003 line into a carbon quote because the panel listed several insecticide names skips the name and skips the fact that the goal on this row is zero.

The goal and the MCL both have to stay on the note, because they do not match. Dropping the zero because it is not a measured result is how a later reader pastes Silvex's matched 0.05 and calls the pages the same. Write both cells. Say the goal is zero and the MCL is 0.003 mg/L. Do not say the zero means the well passed.

An insecticide sentence is easy to widen. Lindane's source cell adds lumber and gardens, and its pair is 0.0002 mg/L on both cells. If the lab names toxaphene, keep cotton and cattle on the source line and keep the zero attached to the goal. Do not average 0.003 with 0.0002 because both names can name cattle.
