A lead-risk map and address list for your area, at no cost.
If you haven't tried methylammonium bromide (MABr) lead dust tests in your program yet, tell me where you work. I'll apply all the public data available for your area, build it for your program at no cost, and send you samples to try.
Where the test fits in programs you already run
You spray a surface or settled dust, shine a UV light, and where lead is present it glows bright green in seconds. Programs use it for things like these.
Fewer failed dust-wipe clearances
Contractors spray and check the work area after cleanup, while there's still time to clean again. Do the check before the final cleaning pass so nothing is left on the surfaces that get wiped.
About one in five first clearances failed in the National Center for Healthy Housing's 2004 evaluation of HUD lead hazard control grantees.
Screening target housing without an EBLL
Check pre-1978 homes in your highest-risk blocks before an elevated blood lead result comes in, so inspector and XRF time goes to the homes most likely to need it.
XRF inspections commonly run $300 to $700 per home.
Interim controls after an EBLL
After interim controls, spray the treated surfaces and sills. If anything still glows, clean again before the lab wipes go out. A clear screen is not a clearance. The lab wipes still decide that.
Home visit education
A parent can see the lead on their own windowsill under the UV light, which makes the lead-safe cleaning and painting advice easier to act on. Leave a kit so they can check again after they clean.
Anything else that means finding lead hazards
Code complaint visits, child care facilities, WIC and prenatal packets. If you have a use in mind that isn't listed, put it in the form.
Free to try first
I send a few sample kits to your field staff and walk them through it on a 20-minute call. Then you decide.
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 where the county publishes build years.
- A ranked list of addresses to start with, oldest and highest-risk first. I send it to your staff directly and it isn't published anywhere.
- 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 a letter documenting the donated kits and data as in-kind match, 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 I've built
I've built pages like these for several health departments and lead programs that bought or are trialing the kit. Each one uses only public records.
Dayton and Montgomery County, OhioZIP-level risk, a house-by-house map, family handouts.
Nebraska, statewideAll 93 counties, every parcel with a build year, state surveillance figures.
North Central District, NebraskaNine rural counties, parcel-level map and a kit portal.
New Jersey, statewideCounty map down to real parcels.
Detroit, MichiganHouse-by-house targeting map, East Side.
Philadelphia, PennsylvaniaHouse-by-house targeting map.
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 I published in AGU GeoHealth (vol. 10, no. 10, October 2026, article e2026GH002053), which was checked against measured childhood blood lead in 11 states. How the model works.
Is it legal?
The map and the lists come from records that counties and federal agencies already publish. I don't use medical records, any child's blood lead result, or owner names. The address list I send a program isn't posted anywhere. The public example maps show only the build year the county assessor already publishes for each parcel. A build year is an estimate of risk, not an inspection.
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 sample kits are free, and there's no purchase required to get them. If you decide to use the kit after trying it, I'll send a quote. W-9, vendor registration, quotes, and sole-source documentation are routine for us.
Ask for your area
Tell me where you work and what you'd use it for. I'll reply within one business day and tell you what data your area has. Nothing about your program goes on a public page unless you ask for it.

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). It is a violation of Federal law to use this product in a manner inconsistent with its labeling and intended use. Risk estimates come from public records and are not an inspection.
