This is an example program page. I've built pages like this from public records for several health departments and lead programs that bought or are trialing the kit. I'll build one for your area too, at no cost.
You tell us the county, city, or ZIP codes you cover. We pull the public records: the year every home was built from the county assessor, Census figures on housing age and poverty, and HUD's lists of federally assisted housing. Older homes are far more likely to have lead paint, so we rank each neighborhood and each home by when it was built, using the model I published in AGU GeoHealth in October 2026 (how the model works).
You get a page like this one for your area, a map down to the individual house where the county publishes build years, a ranked address list sent to your staff directly and not published, printable handouts, and a few free kits to try. All of it is free, with no purchase required.
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, and public maps like this one show only the build year the county assessor already publishes. 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. It is a 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. Full disclosures are on the Safety & Compliance page.
Ohio's lead is in its old houses. Here is where, and a free way to see it.
Most homes here went up before lead paint was banned. This shows where the risk concentrates across Ohio, lets anyone check a ZIP in seconds, and in Franklin County drops all the way down to your actual block, house by house, by the year each one was built. Then a kit makes the lead glow green in the home itself.
Where the risk is, county by county
Every Ohio county, shaded by its lead-exposure risk score. Darker means older housing and tighter budgets, the two things that put lead in kids. Hover or tap one to see it. Columbus sits in Franklin County, which drops down to individual homes.

Highest-need counties, where to start
Score blends Census housing age (share built before 1978) and poverty. It is a screen for where to look, not a test of any one home.

Every shape is a real parcel from the Franklin County Auditor's records. Drag to pan, scroll or pinch to zoom, hover a home for its address and age. Many older records leave the build year blank, shown in gray.
Where this map comes from
I built a model that predicts childhood lead-exposure risk down to the neighborhood, from housing age and Census poverty, and checked it against measured childhood blood-lead in eleven states. It holds up. The model, its code, and the validation data are openly published, and the full write-up is under review at AGU's GeoHealth journal. The lookup below is that model, made usable. Paired with a kit that makes lead glow in an actual home, you go from a map to a confirmed hazard in a single visit.

Area-level screen from ACS housing-age (B25034) and poverty (S1701). It flags where lead is likely, it does not test any one home. That is what the kit is for.

The kit that makes the lead show itself
You spray a painted surface or settled dust, shine a UV light, and any lead glows bright green in seconds. It reads on a windowsill, a porch, a dish, a toy, or paint chips. A home visitor, a WIC nurse, or a parent at the kitchen table can run it off a one-page card.

Two ways to run it, your call
Tracked kits
Every kit carries a code. Families report what they found, and you see the picture build across your area: where the glows are, who wants a follow-up. A live map of the lead you are turning up.
choose thisJust the kits and the info
No portal, no tracking, no strings. We ship kits and the field cards to you, you distribute them your way, and we send along the research and the how-to. Simple.

What the kit is, and is not
Fluoro-Spec is a fast field screen that makes lead visible. It is not an EPA-recognized test kit, and it is not a replacement for XRF or for lab dust-wipe clearance where those are legally required. A glow, or the absence of one, is a field indication, not a lab result. Its purpose is to find the likely lead first, so limited inspector and lab time goes to the homes that need it. More on how that compares to the RRP cleaning card.
