The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Outer-floodplain exposure

ST87thUS92ndDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Full methodology ›The read
Westfield, Massachusetts (ZIP 01085) ranks in the top 40% healthiest ZIPs nationally (12,962nd) and the bottom 16% of Massachusetts (444th).
A profile of give and take, with clear readings each way: distance to an emergency room settles at the national minimum, shared with about 11% of ZIPs. Subsidized affordable housing rests in the top 6.0% nationally, and modeled mammography lands in the top 4.2% nationally. Modeled extreme heat settles at the national minimum, shared with about 19% of ZIPs. Lithium in drinking water rests in the bottom 11.3% nationally. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs. On the other side, modeled transportation noise settles in the top 1.0% nationally, modeled pfas rests in the top 7.5% nationally, and outer-floodplain exposure lands in the top 7.6% nationally. Modeled loud transportation noise settles in the top 10.0% nationally.
Against its neighbors, transportation noise runs far higher than the surrounding ZIPs on this measure. For context, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The closest ZIP that ranks healthier overall is ZIP 01030, just across the boundary.

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 0.49 years of 79.4, 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.
