Arsenic in groundwater
39%
in the top 1.7% nationally
Lower is healthier
ST99thUS98thDefinition & 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 ›Fatal road crashes
1.6 per 100,000 residents per year
in the bottom 5.6% nationally
Lower is healthier
ST8thUS6thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Fine-particle (PM2.5) exceedance
1.5%
in the top 6.3% nationally
Lower is healthier
ST69thUS94thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Energy-cost burden
1.4%
in the bottom 3.1% nationally
Lower is healthier
ST17thUS3rdDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›High blood pressure
27.7%
in the bottom 5.6% nationally
Lower is healthier
ST13thUS6thDefinition & source ›
The estimated share of adults who have been told by a health professional that they have high blood pressure.
Full methodology ›PFAS in drinking water
57.9%
in the top 8.9% nationally
Lower is healthier
ST85thUS91stDefinition & 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.
Full methodology ›Median household income
$121,845
in the top 9.1% nationally
Higher is healthier
ST86thUS91stDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Short sleep
30%
in the bottom 9.7% nationally
Lower is healthier
ST30thUS10thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Dry extreme heat
33.1 days/year
in the top 13.9% nationally
Lower is healthier
ST98thUS86thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Lithium in drinking water
26 µg/L
in the top 36% nationally
Lower is healthier
ST91stUS64thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›The read
On balance, and by the composite measure, West Richland, Washington (ZIP 99353) ranks in the top 21% healthiest ZIPs nationally (6,788th) and the top 29% of Washington (166th), based on limited data; treat as directional.
Strengths and concerns sit side by side across the measures here: fatal road crashes resides in the bottom 5.6% nationally, and modeled energy burden lands in the bottom 3.1% nationally. Modeled high blood pressure registers in the bottom 5.6% nationally, and household income sits in the top 9.1% nationally. Modeled short sleep rests in the bottom 9.7% nationally, transit is in the top 12.1% nationally, and modeled coronary heart disease stands in the bottom 12.1% nationally. On the other hand, modeled arsenic settles in the top 1.7% nationally, fine-particle lies in the top 6.3% nationally, and pfas resides in the top 8.9% nationally.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, 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. 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. For a healthier nearby ZIP overall, look to ZIP 99352, 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

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 1.22 years of 80.6, 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.
