Arsenic in groundwater

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 ›The read
Collins, Georgia (ZIP 30421), overall, ranks in the bottom 22% nationally (24,860th) and the bottom 30% of Georgia (499th).
Taken together, the data gives a genuinely mixed reading: modeled arsenic stands in the bottom 3.8% nationally, modeled pfas rests in the bottom 5.2% nationally, and distance to a Superfund site registers in the top 7.6% nationally. On the other side, modeled humid heat resides in the top 8.2% nationally, poverty settles in the top 10.9% nationally, and crowded housing is in the top 11.6% nationally. Modeled diabetes sits in the top 11.9% nationally, and self-care disability lands in the top 12.2% nationally. Modeled stroke lies in the top 12.8% nationally, and independent living disability stands in the top 13.9% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. ZIP 30420, just across the boundary, comes out healthier overall.

Clean environment, heavy chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 93.9 (top 10%); chronic-disease standing 16.1 — 78 points apart, cleaner on the environment than it is on chronic illness.
Ranked #607 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

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 0.88 years of 76.3, 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.
