The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
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.

Full methodology ›The read
By the composite health measure, Linn, Texas (ZIP 78563) ranks in the bottom 36% nationally (20,625th) and the top 43% of Texas (794th), based on limited data; treat as directional.
What defines this place in the numbers is worth naming first: modeled uninsured registers in the top 1.1% nationally, and arsenic rests in the top 0.8% nationally. Modeled extreme heat stands in the top 1.0% nationally, and humid heat lies in the top 1.3% nationally. PFOS in drinking water lands at the national maximum, slow internet speeds sits in the top 2.1% nationally, and crowded housing is in the top 3.4% nationally. Distance to a nursing home settles in the top 4.2% nationally, and PFAS in drinking water resides at the national maximum. More encouragingly, poverty registers at the national minimum.
Read against the ZIPs closest to it, slow internet speeds runs far higher than the surrounding ZIPs on this measure. To spell things out, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. PFOS in drinking water is a common 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. Close by, ZIP 78504, about 13 miles away, 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 3.41 years of 81.6, 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.
