A lead-risk page and address list for your area, built free.

If you haven't tried methylammonium bromide (MABr) lead dust tests in your program yet, tell me where you work. I'll apply as much of the data that's available for your area as I can, build it for you at no cost, and send you samples.

Where the test fits in programs you already run

You spray a surface or settled dust, shine a UV light, and lead glows bright green in seconds. Programs use it for things like these.

Fewer failed dust-wipe clearances

Contractors spray the work area before the clearance wipes are pulled. Leftover dust shows up while there's still time to clean it, not as a failed clearance and a second trip out.

About one in five first clearances fail (NCHH evaluation of HUD grantees, 2004).

Screening target housing before a child is poisoned

Check pre-1978 homes in your highest-risk blocks without waiting for an elevated blood lead result, at a fraction of the cost of sending an inspector to every door.

An XRF inspection typically runs $300 to $700 per home.

Safer homes sooner after an EBLL

After interim controls, check the treated surfaces right away so the family isn't living with leftover dust while you wait on lab results.

Home visits that stick

When a parent watches their own windowsill light up, the lead-safe cleaning and painting advice gets followed. Leave a kit so they can check again after they clean.

Anything else that means finding lead

Code complaint visits, daycares, dishes and toys brought in by families, WIC and prenatal packets. If your job involves finding lead hazards, it probably fits.

Free to try first

I send a few sample kits to your field staff and walk them through it on a 20-minute call. You decide whether it's worth using after you've tried it.

What I build for your area

You tell me the county, city, or ZIP codes you cover. I pull the public records for that area and put them together for your program.

  • A page for your area, like the examples below, with your local numbers on it.
  • A map down to the individual house, colored by the year each home was built, from county assessor records.
  • A ranked list of addresses to start with, oldest and highest-risk first. I send it to your staff privately. It never goes on a public page.
  • Risk scores by ZIP and neighborhood, with housing age, poverty, and child population from the Census.
  • Federally assisted housing in your area, including public housing, HUD multifamily, and tax-credit properties.
  • Printable handouts for families, and an in-kind match letter if you're on an active HUD grant.

House-level build years are available in 41 states and DC so far. Where a county doesn't publish them, I use Census housing age by ZIP, which covers the whole country.

Pages we've built

We've built pages like these for several health departments and lead programs that bought or are trialing the kit.

Common questions

How does the risk model work?

Older homes are far more likely to have lead paint, so the year a home was built is a strong first guess at where the hazards are. I rank each neighborhood and each home by build year, using the model published in the journal GeoHealth in October 2026 and checked against measured childhood blood lead in 11 states. How the model works.

Is it legal?

Yes. Everything on the map comes from records that counties and federal agencies already publish. I don't use medical records, any individual child's blood lead result, or owner names, and the address lists I send programs stay private. A build year is an estimate of risk, not an inspection, and every page says so.

The kit's active ingredient is made by Fluoro-Spec Inc. under an EPA-authorized Low Volume Exemption under TSCA Section 5 (40 CFR 723.50), and programs buy the finished kit on an ordinary purchase order or card. Full disclosures are on the Safety & Compliance page.

Does it replace XRF or lab dust wipes?

No. It's a fast field screen that makes lead visible. It is not an EPA-recognized test kit and does not replace XRF or lab dust-wipe clearance where those are legally required. Programs use it to decide where to look, to catch dust before clearance, and to show families what they're dealing with.

What does it cost?

The page, the map, the address list, and the samples are free. If you decide to use the kit after trying it, I'll size an order to your program and your fiscal year. Sole-source letters, W-9, vendor forms, and quotes are routine for us.

Fluoro-Spec is a fast field screen that makes lead visible. It is not an EPA-recognized test kit and does not replace XRF or lab dust-wipe clearance where those are legally required. The active ingredient, methylammonium bromide, is manufactured under an EPA-authorized Low Volume Exemption under TSCA Section 5 (40 CFR 723.50).
