The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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.

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.

By its overall health score, Unionville, North Carolina (ZIP 28110) lands in the top 42% healthiest ZIPs nationally (13,487th) and the top 39% of North Carolina (309th).
Taken together, the profile's clearest strengths surface right away: lead in tap water registers in the bottom 9.5% nationally. Distance to a nursing home sits at the national minimum, shared with about 27% of ZIPs. Mental-health providers rests in the top 14.2% nationally. Against that, modeled expected annual loss is in the top 4.9% nationally, disaster risk stands in the top 6.6% nationally, and nitrate settles in the top 8.4% nationally. Modeled industrial-pollution burden lies in the top 13.8% nationally, and pfas resides in the top 14.5% nationally. Distance to a hazardous-chemical facility lands at the national minimum, shared with about 31% of ZIPs. Crowded housing registers in the top 16% nationally.
Weighed against the ZIPs nearby, expected annual loss runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Overall, the nearest healthier neighbor is ZIP 28079, 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 0.48 years of 77.1, 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.
