Mail-in land test kit · $149

Everything you grow comes out of the ground, but you’ve never tested it for toxins.

One sample from the bed, screened for lead, arsenic, cadmium and seven more heavy metals, with plain-language context on where each reading sits.

For people who already pay attention to the ground, and have only ever had it tested for how well things grow.

WHY UNDR

No expert required. Ten minutes, your own mailbox, nobody on your property.

No reading without a next step. What each number means, and what comes next if one stands out.

Detect harmful toxins. Ten heavy metals, lead and arsenic included.

Private and confidential. We never sell your results.

Be the one who checked. The one box the home inspection skipped.

A report you'll want to share. Plain English, your land's type, real comparisons.

Two things show up in the mail.

An open UNDR kit with the shovel, gloves, pouches and prepaid mailer laid out
First—the kit

Shovel, gloves, sterile pouches, prepaid mailer. Dig, seal, drop it in your own mailbox.

Who it's for

You’ve had the soil tested. You’ve never had it looked at.

A county or extension test answers how well things grow—pH, a few nutrients, maybe organic matter. It's the right test, and it's a different question.

“I know how well it grows. I’ve never known what’s in it.”

You built the beds

You know the pH, you amend every spring, and you've never seen a number for anything else that's in there.

The garden came with the house

Somebody else laid it out, filled it and grew in it, and nobody wrote any of that down.

You brought in soil or compost

Bed mix, topsoil and compost all came from somewhere. One sample says what's in the bed you actually have.

You grow food you eat

Which makes what's in the ground worth a number rather than an assumption.

  • 1. Dig

    A small shovel and a card telling you how. Ten minutes. Gloves in the box.

  • Mail-in soil sample kit with envelope and test vials for home land testing

    2. Mail

    Seal the pouch, and drop it in the prepaid envelope.

  • 3. Find out

A garden bed has a history, and it usually isn’t the gardener’s.

“I built the beds myself. I never thought about what was under them.”

Fruit trees were sprayed with lead arsenate into the 1960s, and it stayed in the ground long after the orchards went.1 Deck lumber was preserved with arsenic until the end of 2003, and the ground around an old deck carries that.2 Neither breaks down.3 None of that is a statement about your beds—it's why a number beats a guess.

What we go looking for
Heavy metals—ten of them, including lead, arsenic, mercury and cadmium
The standard elements your sample is made of
Petroleum contaminantsPlus

Three categories of things we can look for. Your kit decides which of them get run, and the report says plainly what showed up and what didn’t.

✗ Not on this report
pH, nitrogen, phosphorus, potassium, organic matter. For those, your county extension office runs the right test for under $30.

The report

This is what comes back.

Not a lab printout. Real pages from real reports:

Your short answer

Two of ten heavy metals showed up, both under the common range. Your land reads Volcanic, and your iron is in the range of samples from Iceland.

Carson and Mari, founders of UNDR
Why this exists

We built the lab because we couldn't get the answer either.

We have a child who puts everything in her mouth, and we wanted to know what was in our land. There wasn't an easy way to find out. That's part of why we built UNDR.

Every sample is run here in the U.S., on the same instrument with the same protocol, and a person reads every report before it goes out.

"I have no idea where to start."

That’s the normal starting point, and the kit assumes it. A small shovel, a card telling you how, and a prepaid mailer are in the box. Ten minutes in your own yard, then your own mailbox. Nobody comes to your property.

"What if it comes back boring?"

Every one comes back with a type, a map, two famous comparisons and a page per element. If yours tells you nothing you didn't already know, email us and we'll refund it.

"What if it comes back high?"

Then you'll know. An elevated number comes with a name, the usual reasons it shows up, and who handles it. A number you never looked up gets none of that.

What the report does.

It tells you what’s in the sample from that bed and how each reading sits against common ranges. And it gives you catered guidance for anything that came up.

Pick your kit.

Every kit ships with the shovel, gloves, pouches, prepaid mailer and the full report.

FREQUENTLY ASKED QUESTIONS

Is this a soil test for growing?

No. There's no pH, no nitrogen, phosphorus or potassium, and nothing about fertility or yield. Your county extension office runs that test and it's usually under $30. This one screens the sample for ten heavy metals and tells you what else it's made of.

Does this tell me whether my vegetables are safe to eat?

No, and nobody can tell you that from a land sample. What we can tell you is what was in the sample from that bed and how each reading sits against the ranges commonly found in soil. If something reads elevated, the report points you to the kind of professional who does certified work.

Does it have to be my land?

Your yard, your parents' place, family land, or anywhere you have permission to dig.

How accurate is it?

Accurate for the sample you send. Lab-grade instruments, recognized methods, and every number shows its own detection limit and margin of error. One scoop doesn't describe a whole property.

When will I get my results?

Three to five business days after your sample reaches the lab, 1-2 on Premium. We post it to your account and email you.

What happens to my information?

We never sell your results.

Which bed should I sample?

The one you grow food in most, or the oldest one if you're picking between them. Root crops and leafy greens sit closest to the question, so that bed is the sensible first sample. You can always send another.

You shouldn’t have to wonder what’s in the ground you grow in.

One sample from the bed, our own U.S. lab, and ten heavy metals read against the ranges commonly found in soil, in plain English.

One scoop at the end of a row, and the ground stops being the part you guess at.
