The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
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.

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
Dublin, Georgia (ZIP 31021) ranks in the bottom 18% nationally (26,213th) and the bottom 23% of Georgia (547th).
Several signals sit on each side of the ledger here: physicians is in the top 5.4% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. Modeled arsenic lies in the bottom 7.4% nationally, and pharmacy is in the top 7.7% nationally. Working the other way, modeled loneliness registers in the top 2.5% nationally, lead in tap water lies in the top 3.9% nationally, and modeled self-care disability is in the top 7.4% nationally. Modeled obesity registers in the top 4.4% nationally, high blood pressure lies in the top 7.1% nationally, and utility shutoff is in the top 8.2% nationally.
Against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. For context, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. The closest ZIP that ranks healthier overall is ZIP 30428, just across the boundary.

Findings that name this ZIP
2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Below what income predicts
The ZIP codes that outlive their incomes
Estimated life expectancy is 73.9 ± 1.4 years. A median household income of $55,697 predicts 77.8 years — 3.9 years below.
Ranked #5,013 of the 5,842 ZIP codes this finding names, ordered by years above what income predicts, highest first.
Clean environment, heavy chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 70.4; chronic-disease standing 14.2 — 56 points apart, cleaner on the environment than it is on chronic illness.
Ranked #2,018 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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 0.70 years of 73.8, 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. How distance is measured
