PCBs in Miami-Dade County Florida Water

Unhealthy Levels of PCBs in the Water Supply of Miami-Dade County Florida Homes

Polychlorinated biphenyls, commonly called PCBs, are industrial chemicals that stick around in the environment and can occasionally be detected in water. These compounds were used in older electrical equipment and various manufacturing processes, and when they make their way into waterways they can be slow to break down. In Miami-Dade County many homeowners first hear about contaminants like PCBs through utility notices, neighborhood conversations—from areas near Downtown Miami or Coral Gables to other parts of the county—or from private water testing, so it’s sensible to know what they are and how they behave.

Because PCBs are usually found at very low concentrations, tap water won’t reveal them by sight, smell, or taste. They can enter drinking water through legacy contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even with clear water coming from your kitchen or bathroom—whether you live near Wynwood, Coconut Grove, or other Miami-Dade neighborhoods—questions about long-term exposure are understandable. Treating water at the whole-house level protects the water used for cooking, bathing, laundry and every daily routine throughout your home.
