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
Walnut, Kansas (ZIP 66780), by its overall standing, sits in the bottom 38% nationally (19,869th) and the bottom 31% of Kansas (471st).
The measures fall on both sides of the ledger for this area: modeled arsenic sits in the bottom 4.5% nationally, modeled transportation noise settles in the bottom 5.7% nationally, and homeownership registers in the top 7.0% nationally. Modeled loud transportation noise stands at the national minimum, shared with about 22% of ZIPs. Crowded housing lands at the national minimum, shared with about 29% of ZIPs. Modeled industrial-pollution burden is in the bottom 15% nationally. Set against that, home broadband subscription resides in the bottom 8.2% nationally, and poverty rests in the top 8.8% nationally. Modeled extreme heat lies in the top 15% nationally, and energy burden sits in the top 12.5% nationally.
Defined in plain terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The nearest ZIP ranking healthier overall is ZIP 66733, 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 0.93 years of 79.0, 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.
