PCBs in Key Largo Park Florida Water

Unhealthy Levels of PCBs in the Water Supply of Key Largo Park Florida Homes

PCBs are industrial chemicals, also called polychlorinated biphenyls, that linger in the environment and can appear in water supplies long after they were used. They were common in older electrical gear and some manufacturing, and when they get into waterways they break down slowly. In Key Largo Park and the surrounding Monroe County area, residents typically hear about PCBs from utility notices, neighborhood conversations, or private water testing—especially given our coastal setting and the potential for sediment movement during storms.

Because PCBs are usually present at trace levels, you won’t detect them by sight, taste, or smell in tap water. They can enter sources through historic contamination, runoff, or disturbed sediments—risks that can be amplified in coastal communities by storm surge or heavy rains. Even when water looks clear in homes near John Pennekamp Coral Reef State Park or along Ocean Reef, people may still want to address long-term exposure for cooking, bathing, and laundering. Treating the whole house protects every tap and appliance, not just a single faucet.
