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 ›The read
Working only from the data in hand, Summer Shade, Kentucky (ZIP 42166) lands in the bottom 4.1% nationally (30,783rd) and the bottom 36% of Kentucky (474th), based on limited data; treat as directional.
What little the measures show is worth setting out plainly: modeled arsenic lies in the bottom 5.0% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Distance to a Superfund site lands in the top 12.1% nationally, and distance to a hazardous-chemical facility registers in the top 15.0% nationally. On the other hand, modeled tooth loss sits in the top 4.4% nationally, poverty rests in the top 5.5% nationally, and modeled short sleep is in the top 10.9% nationally. Crowded housing stands in the top 14.3% nationally, households without a vehicle settles in the top 17% nationally, and fatal road crashes lies in the top 18% nationally.
To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. 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. Overall, the nearest healthier neighbor is ZIP 42124, 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.
Compared with the ZIP codes measured across all nine scoring domains — not with all US ZIP codes.
Nothing measured is lifting this score.

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 0.88 years of 75.0, 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.
