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
Given how limited the coverage is here, Walnut Bottom, Pennsylvania (ZIP 17266) lands in the bottom 35% nationally (20,869th) and the bottom 29% of Pennsylvania (1,245th), based on limited data; treat as directional.
From the measures that are available, a few readings can be named: modeled expected annual loss lies in the bottom 4.8% nationally, and disaster risk lands in the bottom 6.5% nationally. Modeled arsenic sits in the bottom 9.2% nationally, and housing-cost burden is in the bottom 9.6% nationally. On the other side, modeled loud transportation noise settles in the top 1.2% nationally, modeled transportation noise resides in the top 1.9% nationally, and households without a vehicle registers in the top 5.4% nationally. Home broadband subscription rests in the bottom 6.9% nationally. Fiber broadband stands at the national minimum, shared with about 19% of ZIPs. Modeled radon lies in the top 13.4% nationally.
Set beside the nearby areas, loud transportation noise runs far higher than the surrounding ZIPs on this measure. A note on the terms: expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. For a healthier nearby comparison, ZIP 17257, just across the boundary, ranks better overall.
What’s driving this score

Not placed: Chronic Disease Burden and Risk Behavior — too little of each is measured here to compare reliably. They still count toward the score (together 38% of it); we just will not publish a standing we cannot stand behind.
No data: Mental Health and Disability — not measured in this ZIP, so it is left out of the score entirely rather than estimated.

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 1.53 years of 80.6, 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.
