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.

The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

By the composite health measure, ZIP 85143, one of several in San Tan Valley, Arizona ranks in the top 35% healthiest ZIPs nationally (11,362nd) and the top 38% of Arizona (149th).
A number of measures pull each way for this area: floodplain exposure lies at the national minimum, and home broadband subscription lands in the top 9.6% nationally. Lead in tap water sits in the bottom 10.7% nationally, and modeled coronary heart disease is in the bottom 10.9% nationally. Modeled energy burden settles in the bottom 13.5% nationally. Set against that, modeled extreme heat resides in the top 0.3% nationally, lithium in drinking water registers in the top 2.1% nationally, and modeled tree cover rests at the national minimum. Distance to a nursing home stands in the top 10.2% nationally, and modeled humid heat lies in the top 12.9% nationally.
Read against the ZIPs closest to it, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. To spell things out, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Close by, ZIP 85140, 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 0.98 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.
