What are Dioxins and furans?

25 measurements
Dioxins and Furans Soil Test

Dioxins and furans form when chlorine and organic material burn together — structure fires involving treated wood and plastics, wildfire moving through the built edge of a neighbourhood, waste incineration. They bind tightly to soil and to fat, they do not break down meaningfully, and the toxic congeners matter at parts per trillion, which is why this analysis is a different order of work from a standard soil screen.

How to Test

Take small scoops from a few spots across the area you care about, mix them in the bag provided, and seal it. A blend beats a single hole, because contamination in soil is patchy.

Every measurement, explained

At Nestwell, we provide science backed ranges for all the exposures in your home, allowing for personalized suggestions of in home remediation.

25 measures, 1 of them written up by our advisors. Scroll the cards to read each one.

  • 2,3,7,8-TCDD

    What it is

    One of the most toxic man-made chemicals, produced as a byproduct of industrial processes and waste incineration.

    A known human carcinogen — even tiny amounts can cause cancer, reproductive problems, immune damage, and hormonal disruption.

“Detects to” is the method detection limit — the lowest concentration this kit's method can distinguish from zero. The lab may substitute an equivalent or updated method, in which case its limit may differ from the one shown.

Designed To Understand Your Whole House

A single kit answers one question properly rather than several vaguely. Whichever you start with, it is the same lab, the same methods, and the same reporting — so results from one kit sit beside results from the next, in one place, on the same scale.

Accredited labs, regulatory methods

Every sample is analyzed by an accredited environmental lab with the same methods regulatory testing uses.

Numbers with regulatory context

Results come back as a measured value next to the standard it is judged against, not just a "detected".

One box, no home visit

Everything arrives at once and we tell you both where and how to sample, no outside home inspection needed.

How Nestwell Testing Works

How Collection Works

Understand the science –›

  1. Collect

    Take small scoops from a few spots across the area you care about, mix them in the bag provided, and seal it. A blend beats a single hole, because contamination in soil is patchy.

  2. Mail

    Everything goes back in the same box with the prepaid return label. No appointment, nobody in your house, and easy to send back when convenient for you.

  3. Read

    Results land in your Nestwell dashboard in about 15 days, each scored against the standard that applies to it.

A number is only useful next to its limit.

At Nestwell, we provide science backed ranges for all the exposures in your home, allowing for personalized suggestions of in home remediation.

Accredited labs only

Samples are analysed by accredited environmental laboratories using the analytical methods used for regulatory compliance work: the same reading a professional consultant would order.

Each result has a standard

A number on its own is not an answer. The EPA action level for lead in water is 15 ppb; the CDC states there is no safe level of lead exposure for children. Each finding is shown against the limit that applies to it.

Where there is no limit, we say so

The EPA sets no numeric limit for mold, and moisture control is the real remedy. Mold results are reported as what is growing and at what relative level, never as just a pass or a fail.

“Our physical & home environment is a direct determinant of our health, and is immunoregulatory. In a year, we breathe about 6 million times, drink 250 gallons of liquid, and eat almost 2 tons of food, with hundreds of compounds interacting on our skin and immune systems. Small environmental changes make a big difference, especially in early childhood development and for vulnerable adults.”

Frequently Asked Questions

Have questions? Find answers to common customer concerns below.

What does the Dioxins and Furans Soil Test actually measure?

The panel runs 25 measures, covering Dioxins and furans. Every one is listed on this page with its detection limit, so you can check for a specific substance before you buy.

How do I take the sample?

Take small scoops from a few spots across the area you care about, mix them in the bag provided, and seal it. A blend beats a single hole, because contamination in soil is patchy. It takes about 10 minutes, and everything you need comes in the box.

How long until I get results?

The kit reaches you in about 3 days. Once the lab receives your sample, results appear in your Nestwell account in about 15 days. Return shipping is prepaid and included.

Who analyses the sample?

An accredited environmental laboratory, using published analytical methods — the same methods and the same labs used for regulatory and commercial testing. Nestwell does not run the analysis itself.

Why do some substances on the panel have explanations and others do not?

Our advisors have written up 1 of the 25 measures on this panel so far. The rest are still measured, reported and held to the same detection limits — they are listed under "Also measured" until the write-up exists. We would rather show you the gap than fill it with something we have not checked.

What happens if something comes back high?

Your results are shown against the relevant reference values rather than as a bare number, so you can see which measures stand out and by how much. The lab reports what it measured; it does not diagnose, and a lab result is not medical advice.

Can I pay with an HSA or FSA?

Most Nestwell kits are HSA/FSA eligible through Truemed. Eligibility is shown on the kit page at checkout, and where it applies you can pay with pre-tax dollars.
