PFOA in drinking water

ST99thUS99thDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was 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.

ST91stUS91stDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Dental provider access

in the top 9.1% nationally
Higher is healthier
ST94thUS91stDefinition & source ›
The number of dental offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.

ST94thUS89thDefinition & source ›
The number of physicians’ offices located inside this ZIP’s boundary, per 1,000 residents.

ST6thUS12thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›The read
On what the available sources can show, ZIP 40205, one of several in Louisville, Kentucky lands in the top 8.7% healthiest ZIPs nationally (2,764th) and the top 1.4% of Kentucky (10th), based on limited data; treat as directional.
From the measures that are available, a few readings can be named: subsidized affordable housing sits in the top 8.1% nationally, and dental providers is in the top 9.1% nationally. Modeled colon screening settles in the top 7.6% nationally, and physicians resides in the top 10.7% nationally. On the other side, PFOA in drinking water registers at the national maximum, PFAS in drinking water rests at the national maximum, and modeled air-toxics cancer risk stands in the top 6.5% nationally. Modeled expected annual loss lies in the top 8.2% nationally, industrial-pollution burden lands in the top 8.7% nationally, and loud transportation noise sits in the top 10.1% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Close by, ZIP 40207, just across the boundary, ranks healthier 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 0.53 years of 80.7, 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.
