State okays Hernando County's plan to clean up old public works compound

BROOKSVILLE — The state Department of Environmental Protection has approved Hernando County's plan to clean up the contamination at its old Department of Public Works complex in south Brooksville.

The county got word of the approval late Monday in a 12-page letter.

That means that, after five years of testing soil and water for contaminants — a process that has already cost millions of dollars — county officials will soon be able to move forward with cleaning up the toxins and petroleum products left behind on the site.

The county's plan includes a menu of options based on each type and the location of contamination, which is thought to have come from the fuel, solvents and other chemicals once stored on the department's fleet management site.

In the neighborhood where contaminants were found outside the confines of the county's property, the primary plan is to replace contaminated soil with clean fill.

On the property itself, the plan is to allow the existing asphalt pavement, concrete pads and sidewalks to remain to prevent human exposure to the contamination.

In other areas that are not capped and where arsenic was found, soil removal and testing is proposed. Monitoring of wells that have not been affected by petroleum products is proposed, and, for the one well that has shown petroleum contamination, a special chemical oxidant product will be used to remedy the problem.

Other options are provided in each of the areas of contamination if they are needed, but the DEP letter states that additional approvals must be sought from the agency if the county goes another route.

The county will also have to obtain all of the necessary state environmental permits to complete each step of the process and find the proper professionals to do the work. County Administrator David Hamilton said Tuesday he was not sure when the remediation work would begin.
