1,4-Dichlorobenzene in Casselberry Florida Water

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

1,4-Dichlorobenzene is a synthetic chemical that can appear in drinking water and becomes a concern when concentrations are higher than expected. Often called p-Dichlorobenzene, many people first notice it by a sharp, mothball-like smell rather than by name. Because it can affect both odor and the overall feel of water, Casselberry homeowners often choose to treat water where it enters the house so showers, laundry and dishwashing aren’t the only times they’re exposed. A whole-house system treats every tap, helping limit contact during everyday use in homes across Seminole County.

Products like deodorants and moth repellents have historically included this compound, and it can reach drinking water through industrial handling, disposal, or contaminated runoff and groundwater. It tends to persist in typical conditions and won’t always show up as cloudiness—often the first hint is an odor in hot showers or when several fixtures run at once. If you smell something like mothballs around Lake Concord Park, Howell Branch Preserve, or in neighborhoods such as Fern Park or Deer Run, testing will confirm whether 1,4-Dichlorobenzene is present and guide the right treatment for your Casselberry home.
