Industrial-pollution burden
in the top 1.6% nationally
Lower is healthier
ST94thUS98thDefinition & 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.

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

Lower is healthier
ST92ndUS96thDefinition & 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.

ST23rdUS7thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Outer-floodplain exposure
5.5%
in the top 6.6% nationally
Lower is healthier
ST84thUS93rdDefinition & 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 ›Radon
0.7 pCi/L
in the bottom 2.8% nationally
Lower is healthier
ST19thUS3rdDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›PFAS in drinking water
49.4%
in the top 13.8% nationally
Lower is healthier
ST93rdUS86thDefinition & 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 ›The read
Judged by its overall standing, Huffman, Texas (ZIP 77336) sits in the bottom 28% nationally (22,992nd) and the bottom 44% of Texas (1,040th).
A demanding profile, and several measures drive it: modeled industrial-pollution burden lies in the top 1.6% nationally, humid heat registers in the top 3.0% nationally, and air-toxics cancer risk is in the top 4.5% nationally. Modeled colon screening lies in the bottom 6.8% nationally, outer-floodplain exposure registers in the top 6.6% nationally, and modeled mammography is in the bottom 10.1% nationally. Floodplain exposure lies in the top 11.0% nationally, and modeled extreme heat registers in the top 11.5% nationally. Modeled uninsured is in the top 10.3% nationally. On the stronger side, modeled radon lies in the bottom 2.8% nationally.
Placed beside its immediate neighbors, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Put plainly, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. A healthier nearby ZIP overall is ZIP 77345, 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 0.99 years of 76.1, 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.
