1,4-Dichlorobenzene in Conch Key Florida Water

Unhealthy Levels of 1,4-Dichlorobenzene in the Water Supply of Conch Key Florida Homes

1,4-dichlorobenzene is a synthetic chemical that can make its way into drinking water and become a concern when concentrations are elevated. Also called p-dichlorobenzene, many people recognize it by a sharp, mothball-like smell more than the chemical name. Because it can affect taste and odor, Conch Key homeowners often choose to treat water where it enters the house so every tap, shower and appliance sees cleaner water. A whole-house solution reduces the chance of exposure during everyday activities like bathing, laundry, and dishwashing in our tropical maritime climate.

This compound has been used in products such as deodorants and moth repellents and can reach water through handling, disposal, or contaminated runoff. It tends to persist because it doesn’t break down quickly under typical conditions, so you might notice an off-odor in hot showers or when several taps are running even if the water looks clear. In Conch Key and elsewhere in Monroe County, testing is the only way to confirm whether 1,4-dichlorobenzene (p-dichlorobenzene) is present and to determine the right treatment for your home—especially for houses on cisterns or municipal supply in the Keys.
