Arsenic in groundwater

Lower is healthier
ST96thUS98thDefinition & 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.

The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›The read
Chichester, New Hampshire (ZIP 03258), overall, ranks in the top 11.7% healthiest ZIPs nationally (3,723rd) and the top 29% of New Hampshire (70th).
Reading the numbers as a whole, the picture lands somewhere in between: modeled mammography is in the top 2.8% nationally, food insecurity sits in the bottom 5.0% nationally, and transportation lands in the bottom 6.7% nationally. Modeled loneliness lies in the bottom 7.3% nationally, housing insecurity stands in the bottom 8.1% nationally, and fair or poor health rests in the bottom 6.0% nationally. Modeled extreme heat registers at the national minimum, shared with about 19% of ZIPs. Modeled utility shutoff resides in the bottom 9.7% nationally, and tree cover settles in the top 10.5% nationally. On the other side, modeled arsenic is in the top 2.5% nationally.
Defined simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. ZIP 03304, about 4.8 miles away, comes out 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 2.53 years of 81.5, 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.
