1,4-Dichlorobenzene in Miami-Dade County Florida Water

Unhealthy Levels of 1,4-Dichlorobenzene in the Water Supply of Miami-Dade County Florida Homes

1,4-Dichlorobenzene is a synthetic chemical that can sometimes appear in drinking water and becomes a concern when concentrations are elevated. Also called p-Dichlorobenzene, many homeowners recognize it by a sharp, mothball-like smell rather than the chemical name. Because it can affect both odor and perceived water quality, families in Miami-Dade County often choose to treat water where it enters the house so every faucet, shower and appliance is protected.

This chemical has seen use in products like deodorants and moth repellents and can enter water supplies through industrial handling, disposal, or contaminated runoff and groundwater. It tends to persist under typical conditions, so even visually clear water can produce noticeable odors—especially in hot showers or when multiple taps run at once. If you notice unusual smells at your Miami-Dade County home, a professional water test is the best way to determine whether 1,4-Dichlorobenzene is present and what treatment will work.
