PFAS in drinking water
88.8%
in the top 0.6% nationally
Lower is healthier
ST91stUS99thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Humid extreme heat
188.1 days/year
in the top 1.1% nationally
Lower is healthier
ST62ndUS99thDefinition & 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 ›Uninsured (under 65)
21%
in the top 3.9% nationally
Lower is healthier
ST86thUS96thDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.
Full methodology ›PFOS in drinking water

Lower is healthier
ST99thUS99thDefinition & source ›
The share of residents served by public water systems where PFOS, one of the most common “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Industrial-pollution burden
in the top 2.3% nationally
Lower is healthier
ST99thUS98thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Floodplain exposure
57.2%
in the top 2.9% nationally
Lower is healthier
ST82ndUS97thDefinition & 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.
Full methodology ›PFAS in drinking water
100%

Lower is healthier
ST99thUS99thDefinition & source ›
The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Short sleep

The read
Judged by its overall standing, Gibsonton, Florida (ZIP 33534) sits in the bottom 34% nationally (21,210th) and the bottom 27% of Florida (709th).
A demanding profile, and several measures drive it: modeled pfas resides in the top 0.6% nationally, humid heat sits in the top 1.1% nationally, and uninsured stands in the top 3.9% nationally. PFOS in drinking water resides at the national maximum, modeled industrial-pollution burden sits in the top 2.3% nationally, and floodplain exposure stands in the top 2.9% nationally. PFAS in drinking water resides at the national maximum, and modeled short sleep sits in the top 6.3% nationally. Modeled colon screening stands in the bottom 6.5% nationally.

Placed beside its immediate neighbors, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. A healthier nearby ZIP overall is ZIP 33578, 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

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.
