The Florida Department of Environmental Protection (FDEP) provides
funding to remediate affected wells through the Inland Protection
Trust Fund. The funding provides the cost for replacing wells,
connecting to public water supplies, or installing granular
activated carbon (GAC) filters to reduce VOCs to safe levels.
County Health Departments (CHDs) are responsible for maintaining a
current list of FDEP filter systems in their county and conducting
routine sampling to ensure continued equipment operation. The
illustration below shows a typical GAC filter setup. The
effectiveness of carbon filters in removing VOCs is related to: (1)
the type and amount of contaminant, (2) the rate of water usage, and
(3) the type of carbon being used. Large contaminant concentrations
and high water use rates reduce the carbon life. Water entering and
leaving the filter is tested by the CHD every three months or as
specified by the FDEP to ensure that the treatment system is working
properly.
