What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Lead in tap water
15 ppb
in the top 1.0% nationally
Lower is healthier
US99thDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Energy-cost burden
6.1%
in the top 2.6% nationally
Lower is healthier
ST94thUS97thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Transportation noise
0.00%
at the national minimum
Lower is healthier
ST1stUS1stDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Radon
3.4 pCi/L
in the top 5.4% nationally
Lower is healthier
ST85thUS95thDefinition & 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 ›Distance to a Superfund site
65 mi
in the top 7.5% nationally
Higher is healthier
ST86thUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Arsenic in groundwater
17.4%
in the top 8.0% nationally
Lower is healthier
ST76thUS92ndDefinition & 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 ›Fine-particle (PM2.5) exceedance
1.1%
in the top 8.6% nationally
Lower is healthier
ST50thUS91stDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Slow internet speeds
0.64%
in the top 16% nationally
Lower is healthier
ST90thUS84thDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Median household income
$54,306
in the bottom 20% nationally
Higher is healthier
ST6thUS20thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.

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.
This area ranks among the highest 10% of US ZIP codes for both modeled radon and modeled groundwater arsenic.

The read
Iona, Minnesota (ZIP 56141), in overall standing, comes out in the top 49% healthiest ZIPs nationally (15,626th) and the bottom 22% of Minnesota (677th), based on limited data; treat as directional.
A balanced showing across the data, with a few readings each side: modeled transportation noise rests at the national minimum, and distance to a Superfund site settles in the top 7.5% nationally. Modeled loud transportation noise lands at the national minimum, shared with about 22% of ZIPs. Modeled industrial-pollution burden rests in the bottom 11.2% nationally, and short sleep settles in the bottom 13.0% nationally. On the other hand, lead in tap water lands in the top 1.0% nationally, and modeled energy burden rests in the top 2.6% nationally. Modeled radon settles in the top 5.4% nationally, and arsenic lands in the top 8.0% nationally. Modeled fine-particle rests in the top 8.6% nationally.
Defined simply, for reference, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. 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 56122, 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 1.14 years of 79.7, 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.
