Lithium in drinking water
220 µg/L

Lower is healthier
ST96thUS99thDefinition & source ›
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 average number of days per year with a modeled daily high of at least 95 °F.

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.

Full methodology ›The read
Coolidge, Arizona (ZIP 85128), by its overall standing, sits in the bottom 13.9% nationally (27,627th) and the bottom 19% of Arizona (318th).
The data is direct about where this area carries real strain: lithium in drinking water sits in the top 0.3% nationally, modeled extreme heat settles in the top 0.5% nationally, and modeled arsenic registers in the top 1.2% nationally. Modeled mammography stands in the bottom 3.1% nationally, modeled tree cover lands at the national minimum, and unemployment is in the top 5.2% nationally. Crowded housing resides in the top 6.0% nationally, and modeled short sleep rests in the top 6.5% nationally. Modeled uninsured lies in the top 7.0% nationally, and colon screening sits in the bottom 7.6% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The nearest ZIP ranking healthier overall is ZIP 85132, 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 1.46 years of 77.9, 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. How distance is measured
