Fiber broadband
100%
at the national maximum
Higher is healthier
ST99thUS99thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Transportation noise
0.00%
at the national minimum
Lower is healthier
ST1stUS1stDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Floodplain exposure
56.5%
in the top 3.0% nationally
Lower is healthier
ST98thUS97thDefinition & 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 ›Industrial-pollution burden
in the bottom 7.0% nationally
Lower is healthier
ST2ndUS7thDefinition & 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.
Full methodology ›Distance to an emergency room
17.7 mi
in the top 7.4% nationally
Lower is healthier
ST92ndUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Medicare-certified hospital with an emergency room.
Full methodology ›Outer-floodplain exposure
4.4%
in the top 8.2% nationally
Lower is healthier
ST93rdUS92ndDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Expected annual disaster loss
$0
in the bottom 8.3% nationally
Lower is healthier
ST5thUS8thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›PFAS in drinking water
9.8%
in the bottom 8.7% nationally
Lower is healthier
ST8thUS9thDefinition & 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 ›Natural-disaster risk
in the bottom 13.3% nationally
Lower is healthier
ST8thUS13thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Air-toxics cancer risk
20 per million
in the bottom 25% nationally
Lower is healthier
ST1stUS25thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›The read
Given the gaps in coverage here, for Marionville, Virginia (ZIP 23408), health standing is not ranked here — the available data is too limited to place it confidently.
The profile opens on partial but real readings: fiber broadband registers at the national maximum, modeled transportation noise stands at the national minimum, and modeled industrial-pollution burden lands in the bottom 7.0% nationally. Modeled expected annual loss is in the bottom 8.3% nationally, and pfas resides in the bottom 8.7% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise lies at the national minimum, shared with about 22% of ZIPs. Against that, floodplain exposure sits in the top 3.0% nationally, and distance to an emergency room settles in the top 7.4% nationally. Outer-floodplain exposure registers in the top 8.2% nationally.
Held up against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. 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.

|---|---|---|---|
| Life expectancy at birth | 85.2 yr ± 2.79 | 78.9 yr (74.7–82.8) n=31,308 | 77.6 yr (74.5–81.4) n=826 |
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 2.79 years of 85.2, and it’s very unlikely to be off by more than twice that.
