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 read
In its overall standing, Cambridge, Iowa (ZIP 50046) lands in the top 8.6% healthiest ZIPs nationally (2,744th) and the top 2.5% of Iowa (23rd).
Reading the numbers as a whole, the picture lands somewhere in between: modeled short sleep settles in the bottom 1.3% nationally, food insecurity is in the bottom 2.9% nationally, and transportation sits in the bottom 3.2% nationally. Modeled housing insecurity lands in the bottom 3.6% nationally, utility shutoff lies in the bottom 5.7% nationally, and independent living disability stands in the bottom 3.1% nationally. Modeled mobility disability rests in the bottom 5.3% nationally. On the other side, modeled binge drinking registers in the top 1.2% nationally, and arsenic resides in the top 4.8% nationally. Modeled radon settles in the top 8.3% nationally.
Put simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. On the overall standing, ZIP 50073, just across the boundary, ranks healthier.

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 3.19 years of 87.5, 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. How distance is measured
