Ocoee's drinking water comes from deep wells tapping the Floridan Aquifer and is treated and distributed by the city's municipal utility. Like much of Central Florida, the supply generally meets federal safe-drinking-water standards, but testing has detected disinfection byproducts (trihalomethanes and haloacetic acids) from chlorination, as well as low levels of PFAS chemicals that exceed newer, stricter EPA health-based limits. Overall water quality is typical for the region, with no major long-term violations, though PFAS and disinfection byproducts remain the primary concerns.
