Arsenic in groundwater

ST1stUS1stDefinition & 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.

The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

Full methodology ›The read
Overall, Fischer, Texas (ZIP 78623) lands in the top 33% healthiest ZIPs nationally (10,439th) and the top 17% of Texas (312th).
The signals balance out across the profile, strengths against concerns: modeled arsenic lies in the bottom 0.9% nationally, and homeownership lands at the national maximum. Housing-cost burden sits in the bottom 4.7% nationally, and home broadband subscription is in the top 7.6% nationally. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. Household income resides in the top 10.7% nationally. Set against that, modeled extreme heat registers in the top 5.0% nationally, fatal road crashes rests in the top 6.0% nationally, and modeled humid heat stands in the top 7.4% nationally. Distance to an emergency room lies in the top 14.3% nationally.
A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. For a healthier nearby comparison, ZIP 78070, just across the boundary, ranks better overall.

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

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.
