The Sacred Sampling standard

Laboratory data — not estimates.

We're independently operated with no ties to filter companies or remediation firms. Every sample is analyzed by an accredited partner laboratory, and your data is yours.

Accredited-lab analysisEPA-referenced methods on real instruments — ICP-MS, GC-MS, LC-MS/MS.
Chain-of-custody on every kitDocumented traceability from the moment you cap the bottle.
Independent by designWe sell tests, not filters — so there's no incentive to over-report.
Questions, answered

Everything you need to know.

How is this different from a hardware-store test strip?

Strips give you an approximate color read for one or two parameters. Your sample is analyzed by an accredited partner laboratory on real instruments (ICP-MS, GC-MS, LC-MS/MS) that quantify exact concentrations — for PFAS, down to parts-per-trillion — then compare each result against EPA limits. It's the difference between a guess and a measurement.

How does the mail-in process work?

Collect your sample, place the ice pack in the insulated mailer, and ship it out the same day you collect using the prepaid label. Samples are time-sensitive, so same-day shipping matters. You'll receive a digital report with a plain-language interpretation guide.

What exactly comes in the kit?

Certified sample containers (pre-cleaned and preserved), a frozen cooling gel pack, an insulated prepaid return mailer, a pre-printed sample label with a unique Sample ID, a chain-of-custody card, and step-by-step collection instructions. PFAS ships in certified PFAS-free tubes with an ultra-clean protocol.

Which kit should I choose?

Want a quick, affordable look at metals? Heavy Metals. Metals plus key minerals? Metals & Minerals. An everyday all-rounder with bacteria, nitrates, pH and hardness? Essentials (most popular). The broadest chemistry with VOCs? Comprehensive. Worried about "forever chemicals"? PFAS. Want to test everything once? Complete Home Inspection. Or take the 60-second quiz.

Can I use these results for real estate or legal purposes?

Every kit is processed under documented chain-of-custody conditions, which supports use in real estate, compliance, and dispute contexts. Kits are for informational and screening purposes and are not a medical diagnosis.

Do you sell filters or treatment systems?

No — and that's intentional. We're independently operated with no financial ties to filter or remediation companies, so there's no incentive to over-report a problem. You get the data; what you do next is up to you.
