Arsenic in groundwater
24.9%
in the top 4.5% nationally
Lower is healthier
ST88thUS96thDefinition & 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
0.35%

Lower is healthier
ST13thUS9thDefinition & 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
Overall, Ridge Farm, Illinois (ZIP 61870) places in the bottom 36% nationally (20,540th) and the bottom 25% of Illinois (1,032nd).
The measures land in both directions, and neither dominates: floodplain exposure rests in the bottom 8.9% nationally. Crowded housing resides at the national minimum, shared with about 29% of ZIPs. Pulling the other way, modeled arsenic is in the top 4.5% nationally, and households without a vehicle lands in the top 9.2% nationally. Fiber broadband stands at the national minimum, shared with about 19% of ZIPs. Modeled radon registers in the top 15% nationally, modeled obesity settles in the top 11.3% nationally, and unemployment sits in the top 15% nationally. Distance to a hazardous-chemical facility lies at the national minimum, shared with about 31% of ZIPs. Distance to an emergency room rests in the top 17% nationally.
For readers new to these terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Among nearby ZIPs, the nearest healthier one overall is ZIP 47847, 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 1.00 years of 76.5, 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.
