Lithium in drinking water

Definition & source ›

The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.

Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

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.

Several signals sit on each side of the ledger here: lithium in drinking water lands in the bottom 4.9% nationally, and modeled industrial-pollution burden settles in the bottom 6.1% nationally. Distance to a hazardous-chemical facility rests in the top 6.2% nationally, and modeled colon screening lands in the top 6.5% nationally. Modeled cognitive disability settles in the bottom 8.9% nationally. Working the other way, modeled extreme heat rests in the top 1.9% nationally, distance to a community health center lands in the top 7.0% nationally, and modeled high cholesterol settles in the top 4.8% nationally. Modeled humid heat rests in the top 7.7% nationally, and outer-floodplain exposure lands in the top 12.5% nationally.

Against its neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For context, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. The closest ZIP that ranks healthier overall is ZIP 78663, just across the boundary.

“Share” is how much of this ZIP’s score the domain accounts for. Percentages are rounded; higher is healthier in every domain. How the score works, and who it compares you with ›

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.42 years of 81.3, 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.
