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.

The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.

Full methodology ›The read
Dundas, Virginia (ZIP 23938) ranks in the bottom 14.2% nationally (27,515th) and the bottom 9.0% of Virginia (795th).
A balanced set of signals defines this area, not any single one: modeled binge drinking stands in the bottom 4.6% nationally. Unemployment sits at the national minimum, shared with about 15% of ZIPs. Modeled arsenic resides in the bottom 8.2% nationally, and pfas stands in the bottom 9.4% nationally. By contrast, modeled stroke sits in the top 6.0% nationally, tooth loss resides in the top 7.3% nationally, and diabetes stands in the top 6.8% nationally. Modeled mobility disability sits in the top 7.1% nationally, independent living disability resides in the top 8.8% nationally, and energy burden stands in the top 7.0% nationally.
For context, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. Energy burden is the share of household income that goes to home energy bills. The closest ZIP that ranks healthier overall is ZIP 23821, 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 1.24 years of 74.4, 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.
