Arsenic in groundwater

52%

in the top 0.6% nationally

Lower is healthier

ST99th
US99th
Definition & 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.

Several readings make the pressure on this area plain: modeled arsenic settles in the top 0.6% nationally, and walkability rests in the bottom 4.6% nationally. Modeled mammography lands in the bottom 5.9% nationally, and slow internet speeds settles in the top 5.8% nationally. On the encouraging side, modeled air-toxics cancer risk rests in the bottom 2.8% nationally, modeled humid heat lands in the bottom 3.4% nationally, and poverty settles in the bottom 5.4% nationally. Modeled industrial-pollution burden rests in the bottom 5.7% nationally. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Park land settles in the top 10.5% nationally.

Against its neighbors, park land runs far higher 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest ZIP that ranks healthier overall is ZIP 81040, 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

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 1.18 years of 81.0, 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.
