Operational in 2009 200 Million Gallons
of Flow into Naples Bay Treated per Year
Nitrogen Reduced By 81%
Phosphorus Reduced By 37%
Metal Concentrations Reduced to Background Levels
Upper Reach of the
Gordon River Flows into Naples Bay North/Upstream of
the Water Control Structure @ Golden Gate Parkway
Possible Future Opportunities for Additional WQ Improvements
