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
4.2 pCi/L
in the top 1.3% nationally
Lower is healthier
ST99thUS99thDefinition & 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.

18.8%
in the top 2.3% nationally
Lower is healthier
ST95thUS98thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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 ›The read
On the limited readings gathered so far, Greencastle, Pennsylvania (ZIP 17225) lands in the top 38% healthiest ZIPs nationally (12,234th) and the top 34% of Pennsylvania (601st), based on limited data; treat as directional.
What the available data indicates is laid out plainly: outer-floodplain exposure lands at the national minimum, shared with about 36% of ZIPs. Grocery rests in the top 20% nationally, poverty settles in the bottom 23% nationally, and modeled mammography lands in the top 26% nationally. Pharmacy rests in the top 25% nationally. Set against that, modeled radon settles in the top 1.3% nationally, and nitrate lands in the top 2.3% nationally. Distance to a hazardous-chemical facility rests at the national minimum, shared with about 31% of ZIPs. Distance to a Superfund site settles in the bottom 20% nationally, and modeled loud transportation noise lands in the top 23% nationally.
Put plainly, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. A healthier nearby ZIP overall is ZIP 17263, just across the boundary.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts.

Not placed: Chronic Disease Burden and Risk Behavior — too little of each is measured here to compare reliably. They still count toward the score (together 38% of it); we just will not publish a standing we cannot stand behind.
No data: Mental Health and Disability — not measured in this ZIP, so it is left out of the score entirely rather than estimated.

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 1.00 years of 82.6, 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.
