Arsenic in groundwater
65.1%
in the top 0.2% nationally
Lower is healthier
ST94thUS99thDefinition & 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 ›Dry extreme heat
124.9 days/year
in the top 0.7% nationally
Lower is healthier
ST65thUS99thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Lithium in drinking water
180 µg/L
in the top 0.7% nationally
Lower is healthier
ST91stUS99thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Outer-floodplain exposure
23%
in the top 1.8% nationally
Lower is healthier
ST68thUS98thDefinition & 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.

The share of this ZIP’s land area covered by forest.
Full methodology ›Mammography

ST40thUS6thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Distance to a nursing home

ST72ndUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Medicare- or Medicaid-certified nursing home.
Full methodology ›Nitrate in drinking water
0.68%
in the top 7.0% nationally
Lower is healthier
ST96thUS93rdDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams 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 ›Humid extreme heat
137.4 days/year

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›The read
ZIP 85139, one of several in Maricopa, Arizona ranks in the bottom 35% nationally (20,915th) and the bottom 36% of Arizona (254th).
Several readings make the pressure on this area plain: modeled arsenic registers in the top 0.2% nationally, and extreme heat lies in the top 0.7% nationally. Lithium in drinking water is in the top 0.7% nationally, and outer-floodplain exposure registers in the top 1.8% nationally. Modeled tree cover lies at the national minimum, modeled mammography is in the bottom 5.9% nationally, and distance to a nursing home registers in the top 6.9% nationally. Modeled nitrate lies in the top 7.0% nationally, humid heat is in the top 8.0% nationally, and colon screening registers in the bottom 8.4% nationally.
Against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For context, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. The closest ZIP that ranks healthier overall is ZIP 85138, 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 0.74 years of 77.6, 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. How distance is measured
