Nitrate in drinking water

Lower is healthier
ST99thUS95thDefinition & 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.

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.

On the composite measure, Rock Island, Tennessee (ZIP 38581) stands in the bottom 19% nationally (25,934th) and the top 48% of Tennessee (293rd).
A profile of give and take, with clear readings each way: fiber broadband rests in the top 14.6% nationally, and distance to a Superfund site lands in the top 18% nationally. Outer-floodplain exposure settles at the national minimum, shared with about 36% of ZIPs. On the other side, modeled nitrate rests in the top 4.8% nationally, and crowded housing lands in the top 17% nationally. Recreation settles at the national minimum, shared with about 35% of ZIPs. Modeled cognitive disability rests in the top 18% nationally. Physicians lands at the national minimum, shared with about 38% of ZIPs. Households without a vehicle settles in the top 20% nationally. Childcare rests at the national minimum, shared with about 42% of ZIPs.
For clarity, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". ZIP 38544, about 10 miles away, 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 0.78 years of 73.5, 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.
