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.

The main burdens in the data show plainly and lead the picture: distance to a Superfund site stands at the national minimum, modeled pfas is in the top 7.8% nationally, and modeled air-toxics cancer risk rests in the top 8.0% nationally. Modeled expected annual loss sits in the top 8.2% nationally, and slow internet speeds registers in the top 13.7% nationally. More positively, subsidized affordable housing lands in the top 3.3% nationally. Distance to an emergency room resides at the national minimum, shared with about 11% of ZIPs. Transit lies in the top 8.9% nationally, and physicians settles in the top 11.6% nationally. Distance to a nursing home stands at the national minimum, shared with about 27% of ZIPs.

Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 37777, just across the boundary, ranks healthier overall.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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

More ZIPs to explore ▾

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.
