PFAS in drinking water

Lower is healthier
ST1stUS1stDefinition & 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 ›Fine-particle (PM2.5) exceedance
4.7%
in the top 1.2% nationally
Lower is healthier
ST86thUS99thDefinition & 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 ›Industrial-pollution burden
in the bottom 1.6% nationally

ST5thUS2ndDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.

ST20thUS8thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Full methodology ›The read
On the composite measure, Alta, California (ZIP 95701) stands in the top 50% healthiest ZIPs nationally (15,879th) and the bottom 39% of California (1,051st).
A profile of give and take, with clear readings each way: modeled pfas settles in the bottom 0.3% nationally, and industrial-pollution burden rests in the bottom 1.6% nationally. Modeled tree cover lands in the top 4.1% nationally, and floodplain exposure settles in the bottom 8.5% nationally. Park land rests in the top 9.7% nationally. On the other side, modeled fine-particle lands in the top 1.2% nationally, loud transportation noise settles in the top 3.8% nationally, and transportation noise rests in the top 8.8% nationally. Unemployment lands in the top 8.9% nationally. Fiber broadband settles at the national minimum, shared with about 19% of ZIPs.
Set beside the wider area around it, park land runs far lower than the surrounding ZIPs on this measure. For clarity, 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 95631, just across the boundary, ranks better overall among the ZIPs nearby.

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 2.71 years of 81.8, 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. How distance is measured
