The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›The read
From the measures that could be gathered, Gray, Kentucky (ZIP 40734) lands in the bottom 3.3% nationally (31,024th) and the bottom 33% of Kentucky (498th), based on limited data; treat as directional.
So far as the data reaches, a few readings can be drawn: modeled tree cover rests in the top 9.5% nationally, and industrial-pollution burden resides in the bottom 15.0% nationally. Housing-cost burden is in the bottom 17% nationally. By contrast, modeled tooth loss lands in the top 5.4% nationally, PFAS in drinking water stands at the national maximum, and poverty registers in the top 5.5% nationally. Modeled short sleep settles in the top 7.8% nationally, modeled mammography sits in the bottom 10.7% nationally, and household income lies in the bottom 7.3% nationally. Recreation rests at the national minimum, shared with about 35% of ZIPs.
For readers new to these terms, PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Among nearby ZIPs, the nearest healthier one overall is ZIP 40701, just across the boundary.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts.

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 2.05 years of 70.9, 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.
