Arsenic in groundwater

41.2%

in the top 1.5% 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.

Lower is healthier

ST98th

in the top 6.7% nationally

Higher is healthier

ST95th
US93rd
Definition & source ›

The number of services for older adults and people with disabilities inside this ZIP’s boundary, per 1,000 residents.

Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

Full methodology ›

in the bottom 7.6% nationally

Lower is healthier

Reading across the data, the real pressures come first: modeled arsenic sits in the top 1.5% nationally, fine-particle lands in the top 1.5% nationally, and mammography lies in the bottom 5.0% nationally. Walkability stands in the bottom 6.2% nationally, and modeled disaster risk rests in the top 13.2% nationally. More encouragingly, elder services registers in the top 6.7% nationally, and modeled air-toxics cancer risk resides in the bottom 7.6% nationally. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. Distance to an emergency room is in the bottom 11.6% nationally, and distance to a Superfund site sits in the top 12.9% nationally.

Measured against the nearby ZIPs, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 98812, just across the boundary, comes out healthier overall.

“Share” is how much of this ZIP’s score the domain accounts for. Percentages are rounded; higher is healthier in every domain. How the score works, and who it compares you with ›

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 1.28 years of 78.4, 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.
