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
On the data available so far, Herndon, Kentucky (ZIP 42236) lands in the top 49% healthiest ZIPs nationally (15,865th) and the top 8.9% of Kentucky (66th), based on limited data; treat as directional.
The readings that are available are worth naming, coverage aside: modeled arsenic sits in the bottom 4.8% nationally, and poverty resides in the bottom 6.7% nationally. Housing-cost burden stands in the bottom 7.5% nationally, and modeled transportation noise sits in the bottom 10.0% nationally. Modeled loud transportation noise resides at the national minimum, shared with about 22% of ZIPs. Fiber broadband stands in the top 17% nationally. Outer-floodplain exposure sits at the national minimum, shared with about 36% of ZIPs. On the other hand, home broadband subscription resides in the bottom 11.0% nationally. Distance to a hazardous-chemical facility stands at the national minimum, shared with about 31% of ZIPs. Recreation sits at the national minimum, shared with about 35% of ZIPs.
For context, arsenic is a natural groundwater contaminant, 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. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The closest ZIP that ranks healthier overall is ZIP 37043, about 13 miles away.

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 2.91 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.
