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
ZIP 37924, one of several in Knoxville, Tennessee, on the composite measure, lands in the bottom 37% nationally (20,336th) and the top 25% of Tennessee (156th).
Where the data leans one way, another reading answers it: modeled arsenic sits in the bottom 12.1% nationally, floodplain exposure registers in the bottom 24% nationally, and unemployment lands in the bottom 24% nationally. On the other hand, modeled pfas resides in the top 5.5% nationally, air-toxics cancer risk lies in the top 6.9% nationally, and industrial-pollution burden settles in the top 14.3% nationally. Distance to a hazardous-chemical facility stands at the national minimum, shared with about 31% of ZIPs. Modeled humid heat is in the top 17% nationally, and fatal road crashes rests in the top 18% nationally. Childcare sits at the national minimum, shared with about 42% of ZIPs.
Set against the neighboring ZIPs, park land runs far lower than the surrounding ZIPs on this measure. 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier neighbor overall sits at ZIP 37918, 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 0.86 years of 75.1, 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.
