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
Bath, Maine (ZIP 04530), in overall standing, comes out in the top 38% healthiest ZIPs nationally (12,176th) and the top 31% of Maine (126th).
A few readings each way define this mixed profile: subsidized affordable housing rests in the top 7.9% nationally, modeled short sleep settles in the bottom 7.9% nationally, and outpatient lands in the top 9.6% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Modeled humid heat settles in the bottom 10.7% nationally, and recreation lands in the top 11.2% nationally. Civic rests in the top 11.4% nationally. Pulling the other way, modeled arsenic settles in the top 1.3% nationally, and pfas lands in the top 8.0% nationally. Floodplain exposure rests in the top 10.2% nationally.
Defined simply, for reference, 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. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. The closest healthier ZIP overall is ZIP 04011, just across the boundary. Beyond that, the ZIP also sits on the healthier half of the national range on at least seven of the ten good-life measures tracked here, from quiet and green space to nearby care, a combination reached by about one in twenty-five US ZIP codes.

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 0.89 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. How distance is measured
