The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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, Chatsworth, Iowa (ZIP 51011) lands in the top 47% healthiest ZIPs nationally (14,996th) and the bottom 37% of Iowa (580th).
This area's measures are easy to read as a mixed set: fiber broadband sits at the national maximum, housing-cost burden lands at the national minimum, and modeled short sleep lies in the bottom 1.3% nationally. Modeled expected annual loss stands in the bottom 3.7% nationally, disaster risk rests in the bottom 3.8% nationally, and mammography registers in the top 2.4% nationally. Set against that, modeled nitrate resides at the national maximum, and radon settles in the top 4.4% nationally. Modeled transportation noise is in the top 5.4% nationally, and binge drinking sits in the top 6.6% nationally.
Put simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, 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. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. On the overall standing, ZIP 51023, 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 3.73 years of 77.8, 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.
