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.

Full methodology ›The read
By the composite health measure, Casar, North Carolina (ZIP 28020) ranks in the bottom 47% nationally (17,133rd) and the bottom 47% of North Carolina (418th).
The picture here is genuinely mixed, with readings on both sides: lead in tap water lies at the national minimum, and housing-cost burden lands in the bottom 7.2% nationally. Modeled loud transportation noise sits at the national minimum, shared with about 22% of ZIPs. Modeled tree cover is in the top 11.5% nationally, modeled arsenic settles in the bottom 11.8% nationally, and park land resides in the top 12.2% nationally. Modeled transportation noise registers in the bottom 16% nationally, and short sleep rests in the bottom 18% nationally. Outer-floodplain exposure stands at the national minimum, shared with about 36% of ZIPs. On the other side, distance to a nursing home lies in the top 11.7% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Close by, ZIP 28018, just across the boundary, ranks healthier overall.

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 1.16 years of 76.1, 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.
