Lead in tap water
37 ppb
in the top 0.3% nationally
Lower is healthier
US99thDefinition & source ›
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 ›Arsenic in groundwater
20.5%
in the top 6.2% nationally
Lower is healthier
ST86thUS94thDefinition & 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 ›Food insecurity

Full methodology ›Diabetes

The estimated share of adults who have been diagnosed with diabetes.

The estimated share of adults who are blind or have serious difficulty seeing even with glasses.
Full methodology ›Radon
2.7 pCi/L
in the top 16% nationally
Lower is healthier
ST96thUS84thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Fine-particle (PM2.5) exceedance
0.27%
in the top 23% nationally
Lower is healthier
ST97thUS77thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›The read
In its overall standing, Goffstown, New Hampshire (ZIP 03045) lands in the top 13.0% healthiest ZIPs nationally (4,138th) and the top 36% of New Hampshire (87th).
This area's measures are easy to read as a mixed set: modeled food insecurity resides in the bottom 8.7% nationally, and transportation settles in the bottom 8.7% nationally. Modeled extreme heat is at the national minimum, shared with about 19% of ZIPs. Childcare sits in the top 10.7% nationally, and modeled fair or poor health lands in the bottom 8.3% nationally. Household income lies in the top 9.9% nationally, and modeled diabetes stands in the bottom 7.6% nationally. Modeled tree cover rests in the top 11.8% nationally. Set against that, lead in tap water registers in the top 0.3% nationally, and modeled arsenic resides in the top 6.2% nationally.
Against the wider neighborhood, lead in tap water runs far higher than the surrounding ZIPs on this measure. Put simply, 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. On the overall standing, ZIP 03046, just across the boundary, ranks healthier.

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 0.90 years of 80.6, 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. How distance is measured
