The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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 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, ZIP 83607, one of several in Caldwell, Idaho lands in the bottom 40% nationally (19,113th) and the bottom 31% of Idaho (184th), based on limited data; treat as directional.
A number of measures mark where this area is under strain: modeled mammography lands in the bottom 1.4% nationally, and arsenic sits in the top 0.7% nationally. Modeled air-toxics cancer risk is in the top 1.4% nationally, and fine-particle settles in the top 5.0% nationally. Modeled nitrate resides in the top 7.5% nationally, disaster risk registers in the top 9.6% nationally, and extreme heat rests in the top 11.8% nationally. Modeled tree cover stands in the bottom 12.3% nationally. On the brighter side, modeled loneliness lies in the bottom 10.9% nationally. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs.
Set beside the nearby areas, park land runs far higher than the surrounding ZIPs on this measure. A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. For a healthier nearby comparison, ZIP 83617, just across the boundary, ranks better 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 0.53 years of 80.0, 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.
