The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.

Full methodology ›The read
Charlotte, Iowa (ZIP 52731), by its composite score, sits in the top 49% healthiest ZIPs nationally (15,818th) and the bottom 31% of Iowa (637th).
The data opens on a genuinely even set of readings: modeled pfas lands in the bottom 2.5% nationally. Households without a vehicle stands at the national minimum, shared with about 16% of ZIPs. Modeled transportation noise registers in the bottom 10.7% nationally. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. On the other side, modeled binge drinking sits in the top 3.5% nationally, modeled arsenic lies in the top 8.1% nationally, and unemployment rests in the top 8.2% nationally. Modeled radon resides in the top 10.2% nationally, walkability is in the bottom 8.2% nationally, and distance to a community health center lands in the top 14.2% nationally.
For anyone unfamiliar, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. 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. For a healthier comparison close by, see ZIP 52037, 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 2.55 years of 85.2, 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.
