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
In its overall standing, Los Altos, California (ZIP 94024) lands in the top 0.04% healthiest ZIPs nationally (12th) and the top 0.2% of California (3rd).
Reading the numbers as a whole, the picture lands somewhere in between: household income resides at the national maximum, modeled utility shutoff settles in the bottom 0.08% nationally, and modeled food insecurity is in the bottom 0.3% nationally. Modeled housing insecurity sits in the bottom 0.3% nationally, transportation lands in the bottom 0.3% nationally, and obesity lies in the bottom 0.9% nationally. Modeled cognitive disability stands in the bottom 0.3% nationally, and short sleep rests in the bottom 1.2% nationally. Lithium in drinking water registers in the bottom 2.2% nationally. On the other side, outer-floodplain exposure resides in the top 1.0% nationally.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put simply, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". On the overall standing, ZIP 95014, just across the boundary, ranks healthier.

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 0.79 years of 86.2, 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
