Lithium in drinking water
9.1 µg/L

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 ›Nitrate in drinking water
4.0%
in the top 4.6% nationally
Lower is healthier
ST99thUS95thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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 share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were detected in EPA testing.
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
From the partial coverage available here, Bloomfield, Kentucky (ZIP 40008) lands in the bottom 36% nationally (20,468th) and the top 16% of Kentucky (117th), based on limited data; treat as directional.
The readings that are available are worth naming, coverage aside: lithium in drinking water registers in the bottom 0.9% nationally. On the other hand, modeled nitrate lies in the top 4.6% nationally, and PFAS in drinking water is at the national maximum. Modeled pfas registers in the top 13.7% nationally, and walkability lies in the bottom 17% nationally. Recreation is at the national minimum, shared with about 35% of ZIPs. PFOA in drinking water registers in the top 18% nationally, and fatal road crashes lies in the top 19% nationally. Childcare is at the national minimum, shared with about 42% of ZIPs. Park land registers at the national minimum, shared with about 48% of ZIPs.
For clarity, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 40004, just across the boundary, ranks better overall among the ZIPs nearby.

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 1.20 years of 75.1, 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.
