Who it's for

You've checked everything. Almost.

The car seat, the outlet covers, the labels on the food. The yard is the one thing nobody ever gave you an easy way to check: the home inspector wasn't required to test the soil1 and the seller didn't have to say a word about it,2 and it's where they spend the most time.

The last one takes ten minutes and a mailbox.

What shows up at the door

A well-made box, a Saturday in the yard, and a report about your own land.

Digging takes about ten minutes, gloves on. Then seal the pouch, drop it in your own mailbox, and wait for the email.

What the kit screens for

Ten heavy metals. One sample.

The five you've heard of and the five you haven't, each on its own scale in the report with the common range marked.

Lead

Arsenic

Mercury

Cadmium

Chromium

Uranium

Thallium

Antimony

Tellurium

Thorium

The report

What comes back.

A report that walks through your sample element by element in plain English and shows its work. These two readings are from real ones.

What the report said"Arsenic came in over the common range line but under the elevated line, which is more than most soil carries but close to what natural rock holds, so it isn't a rush. Some rock runs this high naturally, and old orchard sprays or treated lumber are the other usual reasons."

Every number shows its detection limit and margin of error. These are screening results on the samples sent to us, not assessments of a property.

Relief when it comes back ordinary. Direction when it doesn't. Either way, in writing.

Why it's worth a look

Every yard has a history. Most of it is ordinary.

Lead paint until 1978,5 leaded gas until 1996,6 arsenic on orchards and in deck lumber until 2003.7,8 None of it breaks down,9 and whether any of it landed in your yard depends on what was there before the house.

A house built before 1978

Old paint settles in the strip of ground along the house, which is where the sandbox usually is.11

A busy road, or an old one

Seventy years of exhaust settled along roadsides and stayed in the top few inches.11

An orchard, or an older deck

Fruit trees were sprayed with lead arsenate,7 and green-tinted deck wood before 2004 was preserved with arsenic.8

3 in 4

What most yards looked like when someone checked

Of 15,595 yards tested nationwide, three in four were under the EPA's lead screening level and one in four were over.4 Nobody could tell which by looking.

Carson and Mari, founders of UNDR
This was our question too

We're Carson and Mari. Our daughter Isabella puts everything in her mouth.

We wanted to know what was in the land she plays on, and there was no easy way to find out. So we built the lab. Every sample is analyzed here in the United States on the same instrument with the same protocol, and a person reads every report before it goes out.

Carson is a veteran with a Master's from Harvard and a B.S. from the U.S. Air Force Academy. Mari has a J.D. from Harvard and a B.A. from Tufts.

"What if it comes back high?"

Then you'll know, and a number you know is a number you can do something about. The report names the usual reasons it shows up and the kind of professional who handles it. The EPA's own first steps for a yard with lead in it are ordinary work.

Straight off the EPA's own list10,9
Cover the bare patches
Raised beds for the vegetables
Shoes off at the door
Wash the hands that were in the dirt

The EPA's list, not our advice. The report points you to the people who give the professional kind.

And if it comes back ordinary, which the numbers say is the more common result,4 you'll have that in writing, and the next time your kid eats a fistful of sandbox you'll be annoyed instead of worried.

FREQUENTLY ASKED QUESTIONS

Is this an EPA-certified test?

No. UNDR is a private lab. Your report is a screening of the exact sample you send, with the detection limit and margin of error shown on every number. If something comes back elevated, the report points you to the kind of professional who does certified work and what to ask them.

Which spot should I test?

The place your kids use most. Bare patches over grass. The strip along the house and the strip along the road are where lead tends to collect, and you can always send another sample.

My kid eats dirt. Is that normal?

Extremely. The EPA's own estimate is that a child between one and six swallows about 100 milligrams of soil and dust in a typical day, more for the committed dirt-eaters, which is the whole reason knowing what's in it is worth ten minutes.

What about the vegetable garden?

Worth testing. Root crops and leafy greens take up lead and arsenic more readily than tomatoes and peppers do, and dirt clings to both, so the garden bed is a sensible second sample.

What about the dog?

Dogs dig, chew and groom, and young animals absorb up to half the lead they swallow, so a dog owner has the same reason to look that a parent does.

How accurate are the results?

Very, and we show you the math. This isn't a color-changing test strip. Your sample is prepared and run on commercial lab-grade instruments using industry-recognized analytical methods, and every result comes with its own detection limit and margin of error.

When will I get my results?

Within 3 to 5 days of your sample reaching the lab, often sooner. We post your report to your UNDR account and email you the moment it's ready.

What happens to my information?

We never sell your results.

Do you test for oil and petroleum?

On the Health & Safety Plus kit and UNDR Premium. Gasoline, diesel, heating oil, motor oil, waste oil, benzene, DDT and more.

You shouldn't have to wonder what's in the land where your kids play.

One sample, our own lab, and a report you can read in one sitting. Ten minutes of it are yours and the rest is ours.
