Arsenic in groundwater

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
By its overall health score, Winthrop, Maine (ZIP 04364) lands in the top 43% healthiest ZIPs nationally (13,837th) and the top 37% of Maine (151st).
Neither strongly one way nor the other, the measures sit mixed: modeled colon screening registers in the top 3.5% nationally. Modeled extreme heat sits at the national minimum, shared with about 19% of ZIPs. Grocery rests in the top 10.1% nationally, modeled binge drinking is in the bottom 11.4% nationally, and homeownership stands in the top 12.7% nationally. Modeled loneliness settles in the bottom 13.3% nationally. Against that, modeled arsenic lies in the top 0.5% nationally, distance to a Superfund site resides at the national minimum, and modeled pfas lands in the top 5.7% nationally. Floodplain exposure registers in the top 13.4% nationally.
To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. 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. Overall, the nearest healthier neighbor is ZIP 04259, 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

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.
