The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›The read
By the composite measure, Mount Union, Iowa (ZIP 52644) sits in the top 43% healthiest ZIPs nationally (13,825th) and the bottom 44% of Iowa (518th).
The profile cuts both ways, and the readings bear that out: lithium in drinking water rests in the bottom 1.6% nationally. Unemployment sits at the national minimum, shared with about 15% of ZIPs. Modeled transportation noise registers in the bottom 10.3% nationally. Modeled loud transportation noise lands at the national minimum, shared with about 22% of ZIPs. Working the other way, PFAS in drinking water resides at the national maximum, and modeled binge drinking lies in the top 6.6% nationally. Modeled radon settles in the top 10.5% nationally. Fiber broadband stands at the national minimum, shared with about 19% of ZIPs. Modeled tree cover is in the bottom 12.8% nationally, and arsenic rests in the top 13.6% nationally.
In plain language, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. ZIP 52640, just across the boundary, ranks healthier overall.

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 1.11 years of 81.2, 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.
