Nitrate in drinking water

Lower is healthier
ST89thUS97thDefinition & 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.

ST97thUS82ndDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Radon

Lower is healthier
ST7thUS20thDefinition & 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.

Overall, Reisterstown, Maryland (ZIP 21136) places in the top 16% healthiest ZIPs nationally (5,166th) and the top 45% of Maryland (207th).
Where the data is kindest to this area, a few readings lead the way: household income lies in the top 10.1% nationally, and modeled hearing disability rests in the bottom 11.0% nationally. Subsidized affordable housing resides in the top 12.7% nationally. Distance to a nursing home is at the national minimum, shared with about 27% of ZIPs. Modeled mammography lands in the top 12.9% nationally, tooth loss stands in the bottom 13.0% nationally, and binge drinking registers in the bottom 17% nationally. On the other hand, modeled nitrate settles in the top 3.2% nationally, loud transportation noise sits in the top 16% nationally, and disaster risk lies in the top 18% nationally.
Beside the areas that surround it, park land runs far lower than the surrounding ZIPs on this measure. For readers new to these terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Among nearby ZIPs, the nearest healthier one overall is ZIP 21030, 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 0.68 years of 80.9, 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.
