ST97thUS95thDefinition & 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.

Full methodology ›The read
Dunstable, Massachusetts (ZIP 01827), overall, ranks in the top 5.0% healthiest ZIPs nationally (1,578th) and the top 19% of Massachusetts (99th).
Taken together, the data gives a genuinely mixed reading: household income settles in the top 0.9% nationally, modeled mammography is in the top 0.5% nationally, and fatal road crashes sits at the national minimum. Modeled obesity lands in the bottom 4.2% nationally, modeled food insecurity lies in the bottom 2.6% nationally, and poverty stands in the bottom 4.8% nationally. Modeled utility shutoff rests in the bottom 5.0% nationally, and home broadband subscription registers in the top 5.6% nationally. On the other side, distance to a Superfund site resides in the bottom 4.3% nationally, and modeled arsenic settles in the top 5.3% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. ZIP 01450, just across the boundary, 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 1.25 years of 82.4, 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.
