ST6thUS1stDefinition & 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.

By its overall health score, Colbert, Georgia (ZIP 30628) lands in the top 45% healthiest ZIPs nationally (14,542nd) and the top 34% of Georgia (240th).
The measures split the difference for this area: modeled arsenic rests in the bottom 1.4% nationally. Distance to a community health center is at the national minimum, shared with about 23% of ZIPs. Distance to a Superfund site stands in the top 13.0% nationally, and home broadband subscription settles in the top 17% nationally. Outer-floodplain exposure lies at the national minimum, shared with about 36% of ZIPs. Unemployment resides in the bottom 21% nationally. Against that, modeled loneliness lands in the top 12.0% nationally, humid heat registers in the top 16% nationally, and pfas sits in the top 17% nationally. Crowded housing rests in the top 23% nationally.
To translate a couple of terms, 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. 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. Overall, the nearest healthier neighbor is ZIP 30683, 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 1.12 years of 77.0, 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.
