Full methodology ›Arsenic in groundwater
30.6%
in the top 3.0% nationally
Lower is healthier
ST99thUS97thDefinition & 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 ›Floodplain exposure
0.00%
at the national minimum
Lower is healthier
ST1stUS1stDefinition & 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 ›Humid extreme heat
6.3 days/year
in the bottom 4.0% nationally
Lower is healthier
ST37thUS4thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›The read
Given the gaps in coverage here, for Fort Harrison, Montana (ZIP 59636), health standing is not ranked here — the available data is too limited to place it confidently.
On what has been documented so far, the readings are limited but real: poverty stands at the national minimum, modeled air-toxics cancer risk lands in the bottom 2.8% nationally, and floodplain exposure is at the national minimum. Modeled humid heat resides in the bottom 4.0% nationally. Working the other way, households without a vehicle rests at the national maximum, and home broadband subscription lies at the national minimum. Housing-cost burden sits at the national maximum, and homeownership settles at the national minimum. Modeled fine-particle registers in the top 1.9% nationally, and arsenic stands in the top 3.0% nationally.
Held up against its neighbors, households without a vehicle runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, 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. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark.

| Life expectancy at birth | 77.8 yr ± 1.69 | 78.9 yr (74.7–82.8) n=31,308 | 79.7 yr (76.7–83.7) n=358 |
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 1.69 years of 77.8, and it’s very unlikely to be off by more than twice that.
