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.

The picture here is genuinely mixed, with readings on both sides: modeled colon screening lies in the top 2.6% nationally, and food insecurity lands in the bottom 6.6% nationally. Modeled extreme heat sits at the national minimum, shared with about 19% of ZIPs. Modeled loneliness is in the bottom 10.3% nationally, tree cover settles in the top 10.6% nationally, and mammography resides in the top 10.1% nationally. Home broadband subscription registers in the top 13.6% nationally. Crowded housing rests at the national minimum, shared with about 29% of ZIPs. Modeled self-care disability stands in the bottom 12.0% nationally. On the other side, modeled arsenic lies in the top 0.8% nationally.

To spell things out, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. This ZIP stands out as the strongest overall among its immediate neighbors.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.64 years of 80.6, 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.
