The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were detected in EPA testing.

Full methodology ›The read
ZIP 77503, one of several in Pasadena, Texas, by its overall standing, sits in the bottom 21% nationally (25,176th) and the bottom 31% of Texas (1,289th).
The profile opens on the burdens that define it most: modeled uninsured stands in the top 0.8% nationally, industrial-pollution burden lands in the top 0.2% nationally, and air-toxics cancer risk is in the top 0.6% nationally. Modeled colon screening resides in the bottom 2.8% nationally, PFOS in drinking water rests at the national maximum, and modeled humid heat lies in the top 4.2% nationally. PFAS in drinking water sits at the national maximum, and outer-floodplain exposure settles in the top 5.9% nationally. Modeled mammography registers in the bottom 7.0% nationally. More positively, subsidized affordable housing stands in the top 1.5% nationally.
Held up against its neighbors, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. The nearest ZIP ranking healthier overall is ZIP 77504, 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 0.61 years of 76.1, 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.
