PFAS in drinking water
81.7%
in the top 1.6% nationally
Lower is healthier
ST99thUS98thDefinition & source ›
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.

Higher is healthier
ST99thUS97thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.

ST97thUS94thDefinition & source ›
The number of civic and social organizations inside this ZIP’s boundary, per 1,000 residents.

The estimated share of women aged 50–74 who had a mammogram within the past two years.

Full methodology ›The read
Given how limited the coverage is here, Loyall, Kentucky (ZIP 40854) lands in the bottom 2.7% nationally (31,224th) and the bottom 29% of Kentucky (529th), based on limited data; treat as directional.
A number of the available measures point to this much: distance to a hazardous-chemical facility rests in the top 2.9% nationally, and modeled industrial-pollution burden stands in the bottom 3.2% nationally. Civic lies in the top 5.6% nationally. On the other hand, modeled pfas lands in the top 1.6% nationally, tooth loss sits in the top 5.1% nationally, and short sleep is in the top 4.5% nationally. Distance to a Superfund site settles in the bottom 4.0% nationally, slow internet speeds resides in the top 4.5% nationally, and modeled mammography registers in the bottom 6.3% nationally. Poverty rests in the top 7.0% nationally.
Set beside the nearby areas, slow internet speeds runs far higher than the surrounding ZIPs on this measure. A note on the 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. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. For a healthier nearby comparison, ZIP 40806, just across the boundary, ranks better overall.
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 1.00 years of 74.5, 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.
