Radon
3.8 pCi/L
in the top 2.6% nationally
Lower is healthier
ST71stUS97thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.

Lower is healthier
ST99thUS98thDefinition & source ›
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
Washta, Iowa (ZIP 51061), on the composite measure, lands in the bottom 49% nationally (16,214th) and the bottom 29% of Iowa (659th).
The main burdens in the data show plainly and lead the picture: modeled radon is in the top 2.6% nationally, modeled nitrate rests in the top 2.4% nationally, and unemployment sits in the top 6.5% nationally. Modeled arsenic registers in the top 7.3% nationally, distance to a community health center lands in the top 7.9% nationally, and modeled fine-particle resides in the top 9.1% nationally. Modeled binge drinking lies in the top 8.8% nationally. More positively, housing-cost burden settles in the bottom 6.4% nationally. Modeled loud transportation noise stands at the national minimum, shared with about 22% of ZIPs. Modeled transportation noise is in the bottom 12.4% nationally.
In everyday language, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier neighbor overall sits at ZIP 51025, 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 1.55 years of 80.9, 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.
