ST17thUS8thDefinition & 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 ›Floodplain exposure
22%
in the top 16% nationally
Lower is healthier
ST98thUS84thDefinition & 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 coverage assembled to date, for Frontier, Wyoming (ZIP 83121), health standing is not ranked here — the available data is too limited to place it confidently.
On the limited coverage here, the data still marks out some readings: modeled humid heat rests in the bottom 1.4% nationally, and air-toxics cancer risk is in the bottom 2.8% nationally. Modeled disaster risk stands in the bottom 4.6% nationally, and distance to a Superfund site settles in the top 5.5% nationally. Modeled pfas lies in the bottom 8.3% nationally. Modeled extreme heat resides at the national minimum, shared with about 19% of ZIPs. On the other side, distance to an emergency room lands in the top 0.9% nationally, distance to a community health center registers in the top 1.7% nationally, and modeled tree cover sits at the national minimum. Fiber broadband rests at the national minimum, shared with about 19% of ZIPs.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup.

Life expectancyNCHS / RWJF USALEEP · model-based
| Measure | Value | US median (p10–p90) | WY median (p10–p90) |
|---|---|---|---|
| Life expectancy at birth | 82.2 yr ± 2.00 | 78.9 yr (74.7–82.8) n=31,308 | 80.7 yr (78.2–83.4) n=168 |
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 2.00 years of 82.2, and it’s very unlikely to be off by more than twice that.
