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.

Overall, Plainview, Tennessee (ZIP 37721) lands in the bottom 32% nationally (21,879th) and the top 30% of Tennessee (182nd).
The picture here is genuinely mixed, with readings on both sides: modeled arsenic lies in the bottom 13.0% nationally, and elder services lands in the top 20% nationally. Modeled transportation noise sits in the bottom 23% nationally, and households without a vehicle is in the bottom 25% nationally. On the other side, modeled industrial-pollution burden settles in the top 11.0% nationally. Recreation resides at the national minimum, shared with about 35% of ZIPs. Modeled pfas registers in the top 18% nationally, humid heat rests in the top 20% nationally, and cognitive disability stands in the top 19% nationally. Modeled expected annual loss lies in the top 26% nationally.
A note on the terms: industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. For a healthier nearby comparison, ZIP 37918, just across the boundary, ranks better overall.

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 76.6, 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.
