Final Legislative Report on the Florida Onsite Sewage Nitrogen Reduction Strategies Study

Final Legislative Report

History

study tasks nitrogen logo

In 2008, the Florida Legislature directed the Department of Health to develop a tool box of cost-effective nitrogen reduction strategies for onsite sewage treatment and disposal systems (OSTDS). The project had two main areas of focus: development of passive nitrogen reduction technologies; and evaluation and prediction of the fate and transport of nitrogen from OSTDS. Objectives included:

  • Development of cost-effective, passive strategies for nitrogen reduction from onsite sewage systems
  • Characterization of nitrogen removal in the soil and shallow groundwater
  • Development of simple models to determine fate and transport of nitrogen from OSTDS in soil and groundwater

In January 2009, the Department in consultation with its Research Review and Advisory Committee (RRAC) contracted with a project team comprised of nationally recognized experts led by Hazen and Sawyer, P.C. The Department, and its RRAC, directed the Florida Onsite Sewage Nitrogen Reduction Strategies (FOSNRS) project, with participation from the Florida Department of Environmental Protection (DEP).
