The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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
By its overall health score, Supai, Arizona (ZIP 86435) lands in the bottom 21% nationally (25,264th) and the bottom 26% of Arizona (293rd), based on limited data; treat as directional.
The measures that define the ground here come first: modeled colon screening rests in the bottom 1.6% nationally, and mammography is in the bottom 1.7% nationally. Distance to a nursing home stands in the top 0.8% nationally, and distance to an emergency room settles in the top 0.8% nationally. Walkability lies in the bottom 0.8% nationally, and slow internet speeds resides in the top 2.2% nationally. On the stronger side, modeled pfas lands in the bottom 0.09% nationally, distance to a hazardous-chemical facility registers in the top 1.2% nationally, and modeled transportation noise sits at the national minimum. Modeled humid heat rests in the bottom 2.4% nationally.
Weighed against the ZIPs nearby, distance to a hazardous-chemical facility runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, 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. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Overall, the nearest healthier neighbor is ZIP 86023, 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 1.93 years of 78.8, 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.
