1,4-Dichlorobenzene in Westchester Florida Water

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

1,4-Dichlorobenzene is a synthetic chemical that can find its way into drinking water and becomes a concern when levels are higher than desired. Also called p-Dichlorobenzene, many people recognize it by a sharp, mothball-like smell more than by name. In Westchester and the wider Miami-Dade County area, homeowners often address it where the water enters the house so odors and quality issues are reduced for bathing, laundry and dishes. Treating water at the point of entry helps limit everyday exposure throughout the home.

This chemical has historically been used in products like deodorants and moth repellents and can reach water through industrial handling, disposal, or runoff that contaminates groundwater. It can be persistent in the environment, so even clear-looking water may still carry an unpleasant odor—especially noticeable in hot showers or when multiple fixtures run. If you notice a mothball-like scent in your Miami-area home or suspect contamination, a water test will confirm if 1,4-Dichlorobenzene is present and point to the right treatment.
