The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
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.

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
With the picture still incomplete, Coldiron, Kentucky (ZIP 40819) lands in the bottom 1.4% nationally (31,643rd) and the bottom 17% of Kentucky (613th), based on limited data; treat as directional.
From the measures on hand, the profile can say a few things: modeled tree cover sits in the top 2.7% nationally, lead in tap water registers at the national minimum, and distance to a hazardous-chemical facility lands in the top 5.9% nationally. Housing-cost burden resides in the bottom 8.0% nationally, and modeled arsenic lies in the bottom 9.3% nationally. Against that, modeled tooth loss settles in the top 2.8% nationally, and short sleep stands in the top 3.9% nationally. Home broadband subscription is in the bottom 6.0% nationally, and household income rests in the bottom 2.4% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs.
In everyday language, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. A healthier neighbor overall sits at ZIP 40810, just across the boundary.
What’s driving this score

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 2.31 years of 76.4, 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.
