Arsenic in groundwater

in the top 1.0% nationally
Lower is healthier
ST99thUS99thDefinition & 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.

Lower is healthier
ST98thUS98thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.

Full methodology ›The read
On the composite measure, Sanford, Colorado (ZIP 81151) stands in the bottom 43% nationally (18,414th) and the bottom 21% of Colorado (399th), based on limited data; treat as directional.
The weightiest signals in the profile are worth naming up front: modeled arsenic rests in the top 1.0% nationally, and energy burden lands in the top 2.2% nationally. Modeled mammography settles in the bottom 6.1% nationally, and crowded housing rests in the top 5.8% nationally. Modeled colon screening lands in the bottom 8.6% nationally. More positively, modeled air-toxics cancer risk settles in the bottom 2.8% nationally, humid heat rests in the bottom 3.8% nationally, and industrial-pollution burden lands in the bottom 4.6% nationally. Distance to a hazardous-chemical facility settles in the top 6.2% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs.
For clarity, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. ZIP 81101, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.81 years of 80.4, 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.
