Arsenic in groundwater
32.6%
in the top 2.7% nationally
Lower is healthier
ST92ndUS97thDefinition & 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 7.8% nationally
Lower is healthier
ST97thUS92ndDefinition & 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.

The read
Armington, Illinois (ZIP 61721), in overall standing, comes out in the top 29% healthiest ZIPs nationally (9,431st) and the top 26% of Illinois (359th).
A healthy showing across the board, and a few measures carry it: home broadband subscription is in the top 6.0% nationally, modeled transportation noise lies in the bottom 6.3% nationally, and homeownership registers in the top 11.2% nationally. Distance to a Superfund site is in the top 11.7% nationally. Crowded housing lies at the national minimum, shared with about 29% of ZIPs. On the other hand, modeled arsenic registers in the top 2.7% nationally, and radon is in the top 7.8% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. Distance to a nursing home registers in the top 14.6% nationally. Distance to a hazardous-chemical facility is at the national minimum, shared with about 31% of ZIPs.
Defined simply, for reference, 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The closest healthier ZIP overall is ZIP 61754, 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 0.98 years of 79.1, 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.
