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 Sullivan County an affordable field test, an advertising rebate to help you recruit inspectors and contractors, and hands-on support along the way.
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.

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.

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 New Hampshire's own numbers through it yet, but every New Hampshire 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 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.
Fluoro-Spec Inc. manufactures the reagent under a U.S. EPA-authorized Low Volume Exemption under TSCA Section 5 (40 CFR 723.50), and the finished kit is sold in commerce today. Public lead programs already purchase it, including New Hampshire DHHS and the City of Columbus. Retail purchase of the finished kit is straightforward; the only thing that is non-transferable is the exemption to manufacture the active ingredient, which stays with us. Full regulatory disclosures, including the methylammonium bromide composition and the TSCA, DEA, and OSHA posture, are on our Safety & Compliance page.
The map shows you where the risk is, and the test confirms it.
I will send Sullivan County 25 kits free to put in the field, no cost and no commitment, so your team can see exactly how it works.
You are in the northeast, so the natural place to meet is the Lead & Healthy Housing Conference in Manchester NH, Nov 3-5, where FluoroSpec will be.

Source: U.S. Census housing records for Sullivan County (NH does not publish home-by-home build years; your Claremont map below is built from local records). Homes built before 1940 carry roughly an 87 percent chance of lead-based paint; 1940 to 1959 about 69 percent; 1960 to 1977 about 24 percent (EPA national survey).
Drag. At about $50 a kit, screening oldest-first from the list above:
5kits a week
→ 260homes a year
→ 226expected lead-positive homes
· about $13,000/yr
Oldest-first means starting in pre-1940 stock, where about 87 of every 100 homes carry lead paint. Blind canvassing in Sullivan County would run nearer 38 in 100. A resident screens the home with the kit and reports what glows; your certified crew follows with XRF only where it glowed. The kit is a screening pre-step, not a substitute for the certified inspection.
For context: your current award works out to about $40,000 per remediated unit. Knowing which door to knock on costs about $50.
What prevention is worth
Published estimates put the lifetime economic value of a single IQ point at roughly $40,000 (Trasande & Liu's figure brought to current dollars; Gould's 2009 estimate runs about $18,000). Childhood lead exposure routinely costs several IQ points. Finding lead before a child is exposed, in the homes most likely to hold it, is the cheapest intervention in this field: a year of weekly screening above costs less than a fraction of what preventing one elevated blood-lead case preserves. That is the primary-prevention side of your grant, stretched.
