Humid extreme heat
205.7 days/year
in the top 0.3% nationally
Lower is healthier
ST90thUS99thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Arsenic in groundwater
1.1%
in the bottom 3.0% nationally
Lower is healthier
ST15thUS3rdDefinition & source ›
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 ›Distance to a Superfund site

in the top 6.9% nationally
Higher is healthier
ST95thUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Floodplain exposure
34.3%
in the top 8.2% nationally
Lower is healthier
ST54thUS92ndDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
This area ranks among the highest 10% of US ZIP codes for both humid-heat days and flood exposure.

The read
By the composite measure, Alva, Florida (ZIP 33920) sits in the top 35% healthiest ZIPs nationally (11,203rd) and the top 46% of Florida (447th).
The readings split fairly evenly between strengths and concerns: modeled arsenic lies in the bottom 3.0% nationally, distance to a Superfund site settles in the top 6.9% nationally, and modeled industrial-pollution burden stands in the bottom 14.1% nationally. Modeled energy burden is in the bottom 13.8% nationally, and households without a vehicle rests in the bottom 16% nationally. Working the other way, modeled humid heat sits in the top 0.3% nationally, and floodplain exposure registers in the top 8.2% nationally. Crowded housing lands in the top 10.7% nationally, and outer-floodplain exposure resides in the top 13.7% nationally. Distance to a hazardous-chemical facility lies at the national minimum, shared with about 31% of ZIPs.
Compared with the ZIPs that surround it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In plain language, 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 33982, just across the boundary, ranks healthier overall.

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

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.
