Arsenic in groundwater

ST1stUS1stDefinition & source ›
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.

The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.

Higher is healthier
ST94thUS92ndDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Pharmacy access
0.39 per 1,000 residents

Full methodology ›The read
Decherd, Tennessee (ZIP 37324), by its overall standing, sits in the bottom 9.5% nationally (29,023rd) and the bottom 22% of Tennessee (479th).
The measures fall on both sides of the ledger for this area: modeled arsenic resides in the bottom 1.4% nationally, grocery rests in the top 7.6% nationally, and pharmacy lies in the top 8.6% nationally. Outpatient sits in the top 12.1% nationally. Set against that, modeled nitrate settles in the top 2.7% nationally, and cognitive disability registers in the top 9.8% nationally. Modeled mobility disability stands in the top 12.2% nationally, and short sleep lands in the top 11.6% nationally. Modeled independent living disability is in the top 13.2% nationally, and distance to a community health center resides in the top 14.2% nationally.
Defined in plain terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. The nearest ZIP ranking healthier overall is ZIP 37330, just across the boundary.

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 0.91 years of 73.9, 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.
