You moved into an older house; any toxins in the yard came with it.
Lead paint until 1978, leaded gas until 1996, arsenic in deck lumber until 2003. None of it breaks down, and whether any of it is in your yard depends on what was here before you. One sample, ten heavy metals, plain-language context on every reading.
For anyone who bought the house and inherited the yard along with it.

Two things show up in the mail.
Shovel, gloves, sterile pouches, prepaid mailer. Dig, seal, drop it in your own mailbox.
Your scoop, element by element, in plain English. Posts to your account days after your sample lands.
The house came with a file. The yard came with nothing.
You got a disclosure, an inspection report and a stack of paperwork about the structure. Not one page of it is about the ground it sits on.
“I asked about the roof and the wiring. I never asked about the yard.”
You bought an older place
Most houses built before 1940 have lead paint on them somewhere, and plenty built before 1978 do too. The strip of ground along the house is where old paint ends up.
The disclosure covered the paint, not the ground
Federal lead disclosure is about the house. Nobody was required to tell you anything about the yard.
There’s a spot the kids actually use
The bare patch under the swing, the sandbox corner, the strip along the drive. That's the sample.
You’re not worried. You just never checked.
If it reads ordinary, that’s worth knowing too.

The house got inspected. The yard came with it.
“I assumed somebody had already checked.”
A home inspector isn't required to look at what's in the soil,1 and federal disclosure covers lead paint in the house rather than the ground around it.2 Not because anyone hid anything—it just was never anybody's job. So whatever is in your yard depends on what was there before the house.
Heavy metals—ten of them, including lead, arsenic, mercury and cadmium
The standard elements your sample is made of
Petroleum contaminantsPlusThree 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.
This is what comes back.
Not a lab printout. Real pages from real reports:
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.
One plain paragraph at the top, before any chart.

Everything screened, on one chart, against the national range.
Readings in every report get lined up against somewhere you've heard of.
What we look for.
Pick a side for $99 or $149. Take both for $299.
Eight precious metals. Plus 17 rare earths—neodymium, yttrium, lanthanum, the ones in your phone and your car—and crude oil.Plus kit
Ten heavy metals. Plus 12 petroleum contaminants—gasoline, diesel, heating oil, motor oil, benzene, DDT.Plus kit
Plus 45 standard elements underneath both, oxygen on up—most of what your land is actually made of. UNDR Premium takes both sides: two samples, 90+ in all.
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.
Not your county soil test.
Four ways to look at a property, and what each one actually tells you.
| Home inspection | Ag soil test | Environmental firm | UNDR | |
|---|---|---|---|---|
| Looks at the land | No | Yes, for farming | Yes | Yes |
| Screens for | Nothing in the yard | pH and a few nutrients | Whatever the bank asks for | 90+ elements, gold to lead |
| Built for | Buyers | Farmers | Developers and lawyers | The person who lives there |
| You get | A PDF you read once | A table of numbers | A binder | Plain-English pages, a type, a map, comparisons |
| Cost | About $400 | Under $30 | Priced for developers | From $99 |
"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.

Four things we promise.
You shouldn’t have to inherit a question along with the house.
One sample from the yard, 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.
