Bisphenol A (BPA) in Key West Florida Water

Unhealthy Levels of Bisphenol A (BPA) in the Water Supply of Key West Florida Homes

Bisphenol A (BPA) is a man-made ingredient used in some plastics and epoxy resins that can occasionally appear in water at very low concentrations. Many people know BPA from food packaging, but it can also touch water during manufacturing, storage, or when plastic components come into contact with plumbing. Because BPA is typically a trace contaminant, you aren’t likely to detect it by taste, smell, or clarity — yet homeowners in Key West often choose to reduce it as part of overall household water care, especially with our coastal climate and salt air affecting fixtures and materials.

BPA is commonly called an emerging contaminant because it may occur at low levels that basic sediment filters don’t capture. It can enter the plumbing system from plastic liners, coatings, or broader environmental sources that influence local waters. Replacing kitchen items with BPA-free alternatives helps in one area, but it won’t treat every faucet in a Key West home — a whole-house filtration strategy ensures more consistent protection for drinking, cooking, bathing, and washing across neighborhoods from Old Town to New Town and beyond in Monroe County.
