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
Smithdale, Mississippi (ZIP 39664), on the composite measure, lands in the bottom 21% nationally (25,224th) and the top 45% of Mississippi (181st).
The readings split fairly evenly between strengths and concerns: unemployment lies at the national minimum, shared with about 15% of ZIPs. Modeled pfas settles in the bottom 9.3% nationally. Working the other way, modeled high blood pressure stands in the top 4.9% nationally, and humid heat is in the top 6.8% nationally. Households without a vehicle rests in the top 6.8% nationally, and poverty sits in the top 7.1% nationally. Home broadband subscription registers in the bottom 8.3% nationally, and modeled mobility disability lands in the top 9.6% nationally. Modeled diabetes resides in the top 10.2% nationally, and stroke lies in the top 10.1% nationally.
In everyday language, 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. A healthier neighbor overall sits at ZIP 39629, 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 1.05 years of 75.8, 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.
