Lower is healthier
ST98thUS88thDefinition & 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 ›Radon
2.4 pCi/L
in the top 23% nationally
Lower is healthier
ST92ndUS77thDefinition & 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 ›The read
Judged by its overall standing, Seymour, Tennessee (ZIP 37865) sits in the bottom 41% nationally (18,773rd) and the top 20% of Tennessee (123rd).
A balanced showing across the data, with a few readings each side: distance to a community health center lands at the national minimum, shared with about 23% of ZIPs. Modeled energy burden rests in the bottom 16% nationally, dental providers settles in the top 19% nationally, and mental-health providers lands in the top 20% nationally. Modeled tree cover rests in the top 21% nationally, and grocery settles in the top 23% nationally. On the other hand, modeled pfas lands in the top 11.8% nationally, and expected annual loss rests in the top 18% nationally. Lead in tap water settles in the top 18% nationally, and modeled humid heat lands in the top 19% nationally.
Placed beside its immediate neighbors, park land runs far lower 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. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. A healthier nearby ZIP overall is ZIP 37803, about 3.4 miles away.

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 0.67 years of 76.8, 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.
