- You are near a former industrial or wood-treatment site
- You want the widest chemical screen available for water
What is in your water?
66 measurements
Semi-volatile compounds are the heavier half of organic chemistry: too heavy to evaporate readily, so they stay in water and soil rather than moving into air. That includes the PAHs left by burning and by asphalt, the phthalate plasticizers that leach out of flexible plastics, wood preservatives like pentachlorophenol, and the residues of older pesticides. They are the compounds a VOC screen is blind to by definition, which is why this panel exists alongside it.
How to Test
Fill the bottles from the tap you drink from, first thing in the morning before anyone has run the water. That first draw is the water that has been sitting in your own pipes overnight, which is where lead and copper show up.
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.

“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
Collect
Fill the bottles from the tap you drink from, first thing in the morning before anyone has run the water. That first draw is the water that has been sitting in your own pipes overnight, which is where lead and copper show up.
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.
Read
Results land in your Nestwell dashboard in about 15 days, each scored against the standard that applies to it.
Why Nestwell?
| Capability | Nestwell | Hardware Store Strips | In Person Inspector |
|---|---|---|---|
| Samples from across your home | Yes | One sample, one place | Yes |
| Real exposure concentrations | Yes | Paper colour key | Sometimes |
| Accredited lab, regulatory methods | Yes | No | Sometimes |
| Nobody has to come into your home | Yes | Yes | No |
| Results tracked over time in one place | Yes | No | One time result |
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.

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 SVOC Water Test actually measure?
The panel runs 66 measures, covering Semi-volatile compounds (SVOCs), Fuel and petroleum compounds, Volatile organic compounds (VOCs) and Plasticizers. 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?
Fill the bottles from the tap you drink from, first thing in the morning before anyone has run the water. That first draw is the water that has been sitting in your own pipes overnight, which is where lead and copper show up. It takes about 5 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 33 of the 66 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.
