1,4-Dichlorobenzene in Hollywood Florida Water

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

1,4-Dichlorobenzene is a synthetic chemical that can appear in drinking water and becomes a worry when concentrations are high. Also called p-Dichlorobenzene, many people first notice it by a sharp, mothball-like smell rather than by name. Because odors and overall water quality can affect daily life — from morning showers near Hollywood Beach to laundry in older homes — many homeowners choose to treat water at the point it enters the house. A whole-house system helps reduce exposure during bathing, dishwashing, and other everyday uses.

This compound has been used in products like moth repellents and some deodorant formulations, and it can enter water supplies through industrial handling, improper disposal, or contaminated runoff and groundwater. It can persist in the environment because it doesn’t break down quickly under typical conditions, and even clear-looking water may reveal an unpleasant odor when you run hot showers or multiple taps. If you notice a mothball-like scent in your home or suspect an issue, testing is the only way to confirm whether 1,4-Dichlorobenzene is present and to determine the right treatment.
