Toxic Secret: Long silent Seminole now says 1,4-dioxane contamination will get worse
After years of staying mostly quiet about a cancer-linked chemical in county drinking water wells, Seminole officials have launched an aggressive effort to get the polluters to clean up what they say is rapidly expanding contamination.
Lawyers hired by the county say the concentration of 1,4-dioxane in the underground water supply —while currently posing no threat to residents — will grow to dangerously high levels in coming years as a toxic plume originating from a defunct telecommunications plant continues its spread west of I-4 into the northwest side of the county. This will come as Seminole’s population and demands for water will grow.
That’s according to a legal petition filed this month in the wake of a state Department of Environmental Protection report in February that for the first time definitively laid the blame for the contamination on General Dynamics, Siemens and MONI Holdings, owners and former operators of the factory site off Rinehart Road.
Seminole agrees with the DEP’s general findings, which are based on extensive chemical fingerprinting of wells tapping the Floridan Aquifer. However, the county says the state report — done in coordination with the Florida Geological Survey — does not go far enough in mandating that the global companies pay to clean up the mess on Seminole’s side.
