Arsenic in groundwater
69.2%
in the top 0.2% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Radon
3.2 pCi/L
in the top 7.6% nationally
Lower is healthier
ST79thUS92ndDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Child-care access
0.48 per 1,000 residents
in the top 11.6% nationally
Higher is healthier
ST90thUS88thDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Colon-cancer screening
59.2%
in the bottom 12.0% nationally
Higher is healthier
ST7thUS12thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Air-toxics cancer risk
20 per million
in the bottom 25% nationally
Lower is healthier
ST1stUS25thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.

The read
New Madison, Ohio (ZIP 45346), on the composite measure, lands in the bottom 36% nationally (20,569th) and the bottom 47% of Ohio (628th).
What the numbers press hardest on defines much of the story here: modeled arsenic is in the top 0.2% nationally, radon rests in the top 7.6% nationally, and colon screening sits in the bottom 12.0% nationally. Recreation registers at the national minimum, shared with about 35% of ZIPs. On the encouraging side, modeled loud transportation noise lands at the national minimum, shared with about 22% of ZIPs. Distance to a community health center resides at the national minimum, shared with about 23% of ZIPs. Childcare lies in the top 11.6% nationally, and modeled disaster risk settles in the bottom 14.0% nationally. Crowded housing stands at the national minimum, shared with about 29% of ZIPs. Outer-floodplain exposure is at the national minimum, shared with about 36% of ZIPs.
Set against the neighboring ZIPs, arsenic runs far higher than the surrounding ZIPs on this measure. In everyday language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. A healthier neighbor overall sits at ZIP 45304, just across the boundary.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 0.67 years of 77.4, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match.
