Lithium in drinking water

Lower is healthier
ST3rdUS1stDefinition & 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.

Full methodology ›The read
Working only from the data in hand, Chaplin, Kentucky (ZIP 40012) lands in the bottom 48% nationally (16,736th) and the top 9.6% of Kentucky (71st), based on limited data; treat as directional.
What little the measures show is worth setting out plainly: lithium in drinking water lands in the bottom 0.9% nationally, and modeled disaster risk registers in the bottom 4.4% nationally. Homeownership sits in the top 8.0% nationally, and distance to a hazardous-chemical facility rests in the top 11.5% nationally. Modeled transportation noise is in the bottom 17% nationally. On the other hand, distance to a nursing home stands in the top 8.8% nationally, and distance to an emergency room settles in the top 9.1% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. Modeled pfas resides in the top 11.5% nationally. Recreation lands at the national minimum, shared with about 35% of ZIPs.
To translate a couple of terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Overall, the nearest healthier neighbor is ZIP 40069, about 3.8 miles away.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts. Compare it against the US, this state and the Louisville/Jefferson County, KY-IN metro area.

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 1.57 years of 74.2, 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.
