Find the lead, and put your grant to work.

FluoroSpec is a low-cost lead-detection kit. You spray a small amount of a reagent (methylammonium bromide) on a surface, and under a UV flashlight it glows bright green wherever there is lead paint or lead dust. I can offer City of Topeka an affordable field test, an advertising rebate to help you recruit inspectors and contractors, and hands-on support along the way.

What I can do for your program

Here are the three main ways I can help.
1
The field test, 25 free to start
The kit glows on lead paint and lead dust under a UV light, so your inspectors can quickly see which units are worth a full XRF reading and a lab sample, and your crews can confirm that dust is gone before and after the work for your RRP records. To get you started, I will send your program 25 kits free.
2
An advertising rebate to grow your crews
When you buy kits, you earn a marketing credit worth 15% of what you spend, which you can use to recruit the inspectors and abatement contractors your area needs. The shortage of trained workers is the main thing that keeps grants from being spent, so this credit goes straight at that problem.
3
Support and collaborative access, wherever you need it
You get the national risk map, your state's validation, and the full method behind our white paper, all for free. We will build a risk map of your county together with you, which you can see described below. We help connect your contractors to training through the Lead and Healthy Housing Conferences. And when you need a hand, you can reach me on the phone. Buying a kit means you get a real person to work with, not just a shipment.

The map is checked against real childhood blood lead

Not a guess. A published method, with the code and data out in the open.
3 to 4×
The top 10% of neighborhoods carry three to four times the state's average rate of lead-poisoned children.
about half
Work just the top fifth of neighborhoods and you reach roughly half of every elevated child in the state.

The map scores every one of the country's 83,388 census neighborhoods from two public Census numbers, the age of its housing and its poverty rate, the two things that most predict where childhood lead exposure concentrates. To check it, we compared that ranking against where children actually test high for lead in eleven states, using blood-lead surveillance the model was never built from. It held in all eleven. The method, the code, and the data are public, so your own epidemiologist can rebuild it and re-check every number.

The eleven states above are the ones where published blood-lead data let us check the map directly. We have not run Kansas's own numbers through it yet, but every Kansas county and neighborhood is scored by the identical method, so the same ranking applies here.

Mint dots are independent tests against data the map was never built from. Blue dots marked * (Michigan, Ohio) re-use the federal study's own surveillance, so they are consistency checks. Bars are 95% confidence intervals where the data support them.

A risk map of your county, down to each home

A regular risk map can point you to a neighborhood. This one can point you to a specific house.

We start with the method we describe in our white paper, which uses the age of housing and local poverty to estimate lead risk. We then sharpen it down to each individual property using the year that home was built. You match that risk layer against your enrollment and waitlist addresses on your own systems, so the names of the families you serve never reach us. What you get back is a ranked list of homes to visit: the oldest and highest-risk homes where children actually live, in the order you should knock on the doors.

The data on your families never leaves your building. We give you the risk layer, and the matching happens entirely on your side. This tells you where to look first. It does not tell you which homes definitely have lead, and the kit is what confirms a hazard on the spot.

The map shows you where the risk is, and the test confirms it.

I will send City of Topeka 25 kits free to put in the field, no cost and no commitment, so your team can see exactly how it works.
