Mail-in land test kit · $149

I’m concerned the ground my dog plays in and eats could have toxic heavy metals.

Dogs dig, chew and groom, and they bring the yard inside on their feet. One sample, ten heavy metals including lead, arsenic and mercury, in plain language. $149.

For the person whose dog treats the yard like a job.

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.

An UNDR report open on a laptop
Then—the report

Your scoop, element by element, in plain English. Posts to your account days after your sample lands.

Who it's for

A dog’s whole day happens at ground level.

Nose down, paws in, lying in the one worn patch, and then straight back through the door onto the couch. Whatever is in the top few inches of that yard is what's in his day.

“He’s out there all day, and I’ve never once known what’s in it.”

A digger

Some dogs have a project going in the same corner for years. That corner is the sample.

More dirt than grass

The worn strip along the fence, the path to the gate, the bare spot by the door. Bare ground beats lawn for a sample.

He goes out, comes in, gets on the couch

Dogs carry the yard inside on their feet, which is how a yard becomes a whole-house question.

A yard you just moved to

You know the dog. You don't know the ground yet.

  • 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

    Receive your report and analysis in your UNDR account portal.

The yard is the one room in the house nobody’s ever looked at.

“I’ve never had a reason to worry. I’ve also never had a way to check.”

Whatever is in a yard has almost nothing to do with how well kept it is—it depends on what was there before the house. Lead paint until 1978,1 leaded gas until 1996,2 arsenic in deck lumber until 2003,3 and none of it breaks down.4 If yours comes back ordinary, that is a perfectly good thing to find out in ten minutes.

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.

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.

Pick your kit.

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

FREQUENTLY ASKED QUESTIONS

Is this a test for my dog?

No. It's a test of a land sample—it tells you what's in the ground he spends his day on, not anything about him. Anything to do with the dog himself is a conversation with your vet, and the report is a useful thing to bring to it.

Which spot should I sample?

Where he digs and where he lies. Bare ground over grass, and the worn patches over the good lawn—that's the ground actually on his paws.

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.

What if something comes back elevated?

Then you'll know, and the report names the usual reasons that element shows up in soil and the kind of professional who does certified work on it. The EPA's own first steps for a yard with lead in it are ordinary work: cover the bare patches, use a doormat, wash up.

You shouldn’t have to wonder about the ground your dog lives on.

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

Relief if it reads ordinary, direction if it doesn’t—3 to 5 business days after your sample reaches the lab.
