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 ›The read
Allyn, Washington (ZIP 98524), by its overall standing, sits in the top 27% healthiest ZIPs nationally (8,793rd) and the top 38% of Washington (218th).
Several readings land clearly in this area's favor and shape the picture: modeled humid heat is in the bottom 6.9% nationally, modeled colon screening resides in the top 6.0% nationally, and homeownership rests in the top 9.2% nationally. Modeled short sleep lies in the bottom 12.0% nationally, home broadband subscription sits in the top 14.6% nationally, and modeled energy burden settles in the bottom 14.3% nationally. Poverty registers in the bottom 17% nationally. Set against that, modeled pfas stands in the top 4.4% nationally, and distance to a nursing home lands in the top 11.0% nationally. Modeled disaster risk is in the top 15% nationally.
Held up against its neighbors, park land runs far lower than the surrounding ZIPs on this measure. Defined in plain terms, 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. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest ZIP ranking healthier overall is ZIP 98546, 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 0.90 years of 79.7, 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.
