Lithium in drinking water
9.3 µg/L
in the bottom 2.4% nationally
Lower is healthier
ST16thUS2ndDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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 ›Humid extreme heat
150.2 days/year
in the top 4.7% nationally
Lower is healthier
ST97thUS95thDefinition & 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 ›Subsidized affordable housing
395 units
in the top 6.0% nationally
Higher is healthier
ST94thUS94thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Floodplain exposure
31.1%
in the top 9.5% nationally
Lower is healthier
ST93rdUS91stDefinition & 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 ›Radon
0.8 pCi/L
in the bottom 6.0% nationally
Lower is healthier
ST2ndUS6thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Outer-floodplain exposure
2.5%
in the top 12.8% nationally
Lower is healthier
ST91stUS87thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Arsenic in groundwater
2.0%
in the bottom 27% nationally
Lower is healthier
ST92ndUS27thDefinition & 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.

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
On balance, and by the composite measure, Kingsland, Georgia (ZIP 31548) ranks in the top 44% healthiest ZIPs nationally (14,055th) and the top 32% of Georgia (227th).
The measures split the difference for this area: lithium in drinking water lies in the bottom 2.4% nationally, and subsidized affordable housing resides in the top 6.0% nationally. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs. Distance to an emergency room registers in the bottom 11.5% nationally, and modeled radon sits in the bottom 6.0% nationally. Against that, modeled humid heat rests in the top 4.7% nationally, floodplain exposure is in the top 9.5% nationally, and outer-floodplain exposure stands in the top 12.8% nationally. Modeled loneliness settles in the top 14.6% nationally. Distance to a hazardous-chemical facility lies at the national minimum, shared with about 31% of ZIPs.
In plainer terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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. For a healthier nearby ZIP overall, look to ZIP 32097, 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 0.77 years of 76.1, 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. How distance is measured
