Nitrate in drinking water

Lower is healthier
ST97thUS99thDefinition & 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.

2.7 pCi/L

Lower is healthier
ST98thUS84thDefinition & 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 ›The read
By its overall health score, Boonsboro, Maryland (ZIP 21713) lands in the top 26% healthiest ZIPs nationally (8,405th) and the bottom 40% of Maryland (276th).
Neither strongly one way nor the other, the measures sit mixed: distance to a nursing home registers at the national minimum, shared with about 27% of ZIPs. Childcare sits in the top 16% nationally, and park land rests in the top 17% nationally. Modeled energy burden is in the bottom 17% nationally, grocery stands in the top 19% nationally, and poverty settles in the bottom 21% nationally. Modeled transportation noise lies in the bottom 22% nationally, and transportation resides in the bottom 22% nationally. Against that, modeled nitrate lands in the top 1.4% nationally, and radon registers in the top 16% nationally.
Weighed against the ZIPs nearby, park land runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Energy burden is the share of household income that goes to home energy bills. Overall, the nearest healthier neighbor is ZIP 21733, 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 0.79 years of 77.9, 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.
