A real reading

This is what your report tells you.

Ten heavy metals screened. Two found in this sample, each with its number and the range it's usually in. Arsenic came in at 13 ppm, under the elevated line.

Every metal we find gets its own page: what it is, where it usually comes from, and what people do next.

My husband and I were very impressed with UNDR’s review of our soil. The results were thorough and we did not have to wait long to get them. The website was very detailed, attractive, and easy to navigate. We will be on the lookout for people we feel could use their services. We wish them success!

The whole Undr experience was top-notch from start to finish. The box it came in, along with everything needed to collect a sample, was very professional and thoughtfully put together. The instructions were clear and easy to follow, and the entire process was both fun and fascinating. I really enjoyed the experience!

As a former science teacher, I absolutely loved seeing the report showing all of the different elements and minerals in my soil. I can definitely see how something like this could help bring chemistry to life for students and make what they’re learning feel more relevant and tangible. The short clips about the different elements are especially educational and engaging. I would encourage everyone to give it a try, but especially science teachers—I think it would be a wonderful resource for the classroom!

FREQUENTLY ASKED QUESTIONS

Will UNDR work in my yard?

Yes. UNDR tests are designed to analyze typical soil material from any geographic or geological region. This includes dense clay soils, sandy areas, rich fertile fields, dry dusty lands and everything in between. See our Sampling Instructions for spots people generally test based on what they are looking for.

Testing for lead in particular? Our guide, How to Test Your Soil for Lead, walks through where to dig and how deep.

Is UNDR safe for kids?

UNDR is a great all-family activity, and even supervised little kids can help. Make sure to follow soil sampling instructions carefully to get reliable results.

What if I want to test more than one area?

UNDR Premium and Plus kits allow you to analyze up to two different soil samples for specified components. UNDR basic kits allow you to analyze one soil sample. Please see individual product pages for specific kit inclusions. For larger-scale testing, we recommend purchasing multiple kits. Remember to document where you dig! If you’re not sure which kit(s) to purchase for your needs, contact us and we’ll be happy to help.

Each test analyzes only the specific sample submitted and may not represent broader property conditions.

What should I do if my report shows precious metals, oil or contamination?

UNDR kits are a fun and educational first step in understanding your land. In addition to data about your land samples, your report will include suggestions for reputable resources and ways to find professionals to advise on next steps.

UNDR provides an informational analysis of your specific soil sample only. Results are educational and do not constitute professional geological, environmental, legal, health, or safety advice. UNDR does not determine the presence of economically recoverable deposits, contamination, regulatory compliance, health risks, or property conditions. Consult qualified professionals, including geologists, environmental consultants, and legal advisors, before making any decisions regarding your property.

What makes an UNDR report different from a traditional soil test?

Traditional soil tests are built for agriculture and focus on a small set of nutrients. They tell farmers what to fertilize—not homeowners what they should know.

UNDR reports go much further—testing for 50+ elements in every kit (over 90 elements and substances with UNDR Premium) and turning complex data into a clear, engaging, and easy-to-understand visual experience. Instead of just numbers, you get real insight into what’s in your soil sample and why you should care.
