Arsenic in groundwater

ST64thUS92ndDefinition & 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
Berwick, Maine (ZIP 03901) ranks in the top 29% healthiest ZIPs nationally (9,273rd) and the top 23% of Maine (94th).
The strongest marks in the data are worth naming first: modeled mammography is in the top 6.4% nationally, and food insecurity registers in the bottom 12.2% nationally. Modeled diabetes lies in the bottom 9.4% nationally, and poverty is in the bottom 14.8% nationally. Modeled mobility disability registers in the bottom 14.2% nationally, distance to a hazardous-chemical facility lies in the top 16% nationally, and modeled vision disability is in the bottom 10.2% nationally. On the other side, modeled arsenic registers in the top 7.9% nationally, distance to a Superfund site lies in the bottom 8.6% nationally, and modeled binge drinking is in the top 14.1% nationally.
Against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. For context, 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. 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. The closest ZIP that ranks healthier overall is ZIP 03869, 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.
