PFAS in drinking water

Lower is healthier

ST98th
US89th
Definition & source ›

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.

An even profile, with readings pulling both ways: outpatient lands in the top 11.2% nationally, and mental-health providers rests in the top 13.1% nationally. Distance to a nursing home settles at the national minimum, shared with about 27% of ZIPs. Modeled energy burden lands in the bottom 16% nationally. Against that, modeled air-toxics cancer risk rests in the top 8.4% nationally, and pfas settles in the top 11.1% nationally. Distance to a hazardous-chemical facility lands at the national minimum, shared with about 31% of ZIPs. Modeled humid heat rests in the top 17% nationally, and distance to a Superfund site settles in the bottom 17% nationally. Crowded housing lands in the top 19% nationally.

Set within its surrounding area, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, for reference, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. 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. The closest healthier ZIP overall is ZIP 37737, just across the boundary.

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

Life expectancy unavailable for this ZIP — fewer than 80% of the census tracts that make it up could be matched across the 2010→2020 tract-boundary revision, so no value is published rather than an unreliable one. See how coverage gaps are handled.
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.
