Arsenic in groundwater

ST26thUS5thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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.

By the composite measure, Hamilton, Georgia (ZIP 31811) sits in the top 21% healthiest ZIPs nationally (6,644th) and the top 14.7% of Georgia (104th).
Where this area does well, the measures make it plain: modeled arsenic resides in the bottom 5.3% nationally, mental-health providers lies in the top 6.1% nationally, and civic settles in the top 6.3% nationally. Modeled tree cover stands in the top 7.8% nationally. Households without a vehicle is at the national minimum, shared with about 16% of ZIPs. Distance to a Superfund site rests in the top 10.9% nationally, and modeled hearing disability sits in the bottom 19% nationally. Against that, fatal road crashes registers in the top 13.6% nationally, and modeled humid heat lands in the top 14.8% nationally. Unemployment resides in the top 16% nationally.
In plain language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. ZIP 31804, 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 1.11 years of 80.1, 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.
