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.

Higher is healthier
ST94thUS97thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
By the composite health measure, Chatham, Massachusetts (ZIP 02633) ranks in the top 4.6% healthiest ZIPs nationally (1,455th) and the top 17% of Massachusetts (90th), based on limited data; treat as directional.
The signals balance out across the profile, strengths against concerns: modeled colon screening rests in the top 0.4% nationally, and housing insecurity stands in the bottom 1.6% nationally. Elder services lies in the top 1.7% nationally, and modeled short sleep lands in the bottom 1.4% nationally. Modeled mammography sits in the top 1.2% nationally, food insecurity is in the bottom 2.4% nationally, and transportation settles in the bottom 2.6% nationally. Distance to a hazardous-chemical facility resides in the top 3.4% nationally, and recreation registers in the top 3.5% nationally. Set against that, modeled pfas rests in the top 1.5% nationally.
Read against the ZIPs closest to it, elder services runs far higher than the surrounding ZIPs on this measure. To spell things out, 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. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Close by, ZIP 02659, 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 1.01 years of 80.4, 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. How distance is measured
