1,4-Dichlorobenzene in Everglades Florida Water

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

1,4-Dichlorobenzene is a synthetic chemical that can sometimes be found in drinking water and becomes a worry when concentrations are elevated. Also called p-Dichlorobenzene, homeowners often notice it first because of a sharp, mothball-like odor rather than the chemical name. Because it can affect both smell and overall water quality, many Everglades residents choose to address it where water enters the house. A whole-house system treats every faucet and shower, helping limit exposure during everyday uses like bathing, laundry, and dishwashing in this coastal, often hard-water region.

This chemical has been used historically in moth repellents and deodorizers and can reach water supplies through industrial handling, disposal, or contaminated runoff and groundwater. It tends to persist because it does not break down quickly under normal conditions, so even clear water can carry an unpleasant odor—especially noticeable in hot showers or when multiple taps run. In Everglades homes, where coastal flooding and storm impacts can increase sediment and corrosion concerns, testing your water is a practical first step to confirm whether 1,4-Dichlorobenzene or p-Dichlorobenzene is present and to determine the appropriate treatment.
