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
Overall, Firth, Idaho (ZIP 83236) places in the top 32% healthiest ZIPs nationally (10,410th) and the top 27% of Idaho (72nd), based on limited data; treat as directional.
The measures land in both directions, and neither dominates: modeled air-toxics cancer risk sits in the bottom 7.7% nationally, and humid heat lies in the bottom 8.9% nationally. Modeled industrial-pollution burden rests in the bottom 12.2% nationally, and loneliness resides in the bottom 14.1% nationally. Poverty is in the bottom 14.9% nationally. Pulling the other way, walkability lands in the bottom 2.1% nationally, modeled fine-particle stands in the top 7.8% nationally, and home broadband subscription registers in the bottom 9.3% nationally. Modeled mammography settles in the bottom 11.7% nationally, and slow internet speeds sits in the top 15% nationally.
For readers new to these terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Among nearby ZIPs, the nearest healthier one overall is ZIP 83274, 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 1.02 years of 79.7, 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.
