Natural Treatment Capacity of Wetlands &

Tailing Sand Filtration on Mined Phosphate Lands

      SI conducted a four-year pilot study to assess the feasibility of using a wetland on mined phosphate lands to naturally purify storm water and reclaimed water to meet drinking water standards.  The system was installed as part of the pilot project funded by the Florida Institute of Phosphate Research (FIPR) and the Southwest Florida Water Management District (SWFWMD).  

      The basic premise of the pilot project is that natural systems, in particular natural water treatment in constructed wetlands created on formed clay settling areas followed by filtration through tailing sand, will remove organic, inorganic and microbiological contaminants and the treated water will meet all drinking water standards.  Throughout the pilot project, the system was successful in meeting all Primary Drinking Water Standards.  Secondary Drinking Water Standards were occasionally exceeded for seven parameters.
