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
Judged by its overall standing, Summerfield, Florida (ZIP 34491) sits in the top 49% healthiest ZIPs nationally (15,841st) and the bottom 42% of Florida (569th).
An even profile, with readings pulling both ways: modeled arsenic lands in the bottom 0.6% nationally, binge drinking rests in the bottom 4.9% nationally, and colon screening settles in the top 4.2% nationally. Against that, modeled humid heat lands in the top 1.1% nationally, coronary heart disease rests in the top 3.0% nationally, and high cholesterol settles in the top 3.0% nationally. Modeled pfas lands in the top 4.8% nationally, and hearing disability rests in the top 5.6% nationally. Modeled stroke settles in the top 10.1% nationally, and expected annual loss lands in the top 13.3% nationally.
Put plainly, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. A healthier nearby ZIP overall is ZIP 32159, just across the boundary.

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 0.53 years of 76.9, 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.
