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.
Radon
4.5 pCi/L
in the top 0.9% nationally
Lower is healthier
ST98thUS99thDefinition & 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 ›Recreation access
2.1 per 1,000 residents
in the top 1.5% nationally
Higher is healthier
ST99thUS99thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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 ›Fiber broadband
99.7%
in the top 2.6% nationally
Higher is healthier
ST87thUS97thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Distance to a Superfund site
84.2 mi
in the top 4.7% nationally
Higher is healthier
ST41stUS95thDefinition & 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 ›Walkability
1.8 intersections/sq mi
in the bottom 6.2% nationally
Higher is healthier
ST53rdUS6thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Distance to a community health center
21.8 mi
in the top 7.2% nationally
Lower is healthier
ST65thUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest federally funded community health center, which serves patients regardless of ability to pay.
Full methodology ›Industrial-pollution burden
in the bottom 7.4% nationally
Lower is healthier
ST10thUS7thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Transportation noise
0.12%
in the bottom 8.8% nationally
Lower is healthier
ST17thUS9thDefinition & 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 ›Fine-particle (PM2.5) exceedance
0.93%
in the top 9.8% nationally
Lower is healthier
ST62ndUS90thDefinition & 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 ›PFAS in drinking water
10.3%
in the bottom 9.9% nationally
Lower is healthier
ST12thUS10thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›The read
By the composite health measure, Delmont, South Dakota (ZIP 57330) ranks in the bottom 39% nationally (19,621st) and the bottom 19% of South Dakota (290th), based on limited data; treat as directional.
A number of measures mark where this area is under strain: modeled radon rests in the top 0.9% nationally, and walkability stands in the bottom 6.2% nationally. Distance to a community health center lies in the top 7.2% nationally, and modeled fine-particle lands in the top 9.8% nationally. On the brighter side, recreation sits in the top 1.5% nationally, fiber broadband is in the top 2.6% nationally, and distance to a Superfund site settles in the top 4.7% nationally. Modeled industrial-pollution burden resides in the bottom 7.4% nationally. Households without a vehicle registers at the national minimum, shared with about 16% of ZIPs. Modeled transportation noise rests in the bottom 8.8% nationally.
To spell things out, 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Close by, ZIP 57313, just across the boundary, ranks healthier overall.

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 0.79 years of 80.8, 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.
