PFAS in drinking water

ST99thUS99thDefinition & source ›
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.

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.

Lower is healthier
ST3rdUS10thDefinition & 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
Luttrell, Tennessee (ZIP 37779), by its composite score, sits in the bottom 13.5% nationally (27,764th) and the bottom 36% of Tennessee (396th).
The measures fall on both sides for this area, fairly evenly: fatal road crashes resides in the bottom 9.6% nationally, and modeled tree cover is in the top 13.3% nationally. Distance to a hazardous-chemical facility lands in the top 19% nationally. Pulling the other way, PFAS in drinking water stands at the national maximum, modeled cognitive disability registers in the top 7.8% nationally, and modeled industrial-pollution burden settles in the top 8.4% nationally. Modeled independent living disability sits in the top 14.6% nationally, and fair or poor health lies in the top 17% nationally. Recreation rests at the national minimum, shared with about 35% of ZIPs. Physicians resides at the national minimum, shared with about 38% of ZIPs.
For anyone unfamiliar, 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. 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.

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 0.85 years of 73.1, 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.
