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 ›The read
Martin, Georgia (ZIP 30557) ranks in the bottom 36% nationally (20,438th) and the bottom 48% of Georgia (367th).
A profile of give and take, with clear readings each way: modeled arsenic rests in the bottom 1.5% nationally. Outer-floodplain exposure lands at the national minimum, shared with about 36% of ZIPs. On the other side, modeled pfas settles in the top 4.7% nationally, distance to a nursing home rests in the top 14.6% nationally, and modeled loneliness lands in the top 17% nationally. Physicians settles at the national minimum, shared with about 38% of ZIPs. Childcare rests at the national minimum, shared with about 42% of ZIPs. Modeled high cholesterol lands in the top 20% nationally, and humid heat settles in the top 24% nationally. Park land rests at the national minimum, shared with about 48% of ZIPs.
For context, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". The closest ZIP that ranks healthier overall is ZIP 29643, about 1.6 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 0.73 years of 76.2, 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.
