Science Plan 22

Slide 23

Science Plan: Purpose and Objectives Consent Orders and Framework Agreement require SFWMD to develop and implement a Science Plan Purpose and Objectives: Identify the key factors that collectively influence phosphorus reduction and treatment performance in order to meet the WQBEL at each STA Identify studies that investigate these key factors that influence phosphorus treatment performance Focus on better understanding design and operations that sustain low outflow phosphorus concentrations (

Slide 24

Science Plan: Progress to Date Final Science Plan submitted to FDEP (June 7, 2013) Science Plan implementation ongoing Detailed Study Plans for 8 Science Plan studies updated in Sep. 2014 17 Technical Representatives (Tech Reps) meetings/ workshops held (Nov. 2012 Feb. 2015) More than 15 private firms and universities under contract to provide technical support and specialized expertise 24

Slide 25

Science Plan: Path Forward Continue to implement Science Plan Review relevant literature Collect field data Continue to analyze data Complete refurbishment of STA-1W Test Cells Continue to have Tech Reps meetings every six (6) months, or more often if needed Next meeting is scheduled for Mar. 26, 2015 Communicate preliminary results to Tech Reps 25

Slide 26

Downstream Monitoring 26

Slide 27

Downstream Monitoring: Summary Purpose: Characterize the effects of STA discharges on the receiving water bodies All monitoring completed to date is in accordance with the Consent Orders Some downstream monitoring was required by previous STA permits and Administrative Orders 27

Slide 28

Downstream Monitoring: Locations Transect Locations 28

Slide 29

Downstream Monitoring: Water Quality Total Phosphorus Summary TP gradient exists from perimeter canals (higher TP) to interior marsh (lower TP) TP gradient characteristics are different in each Water Conservation Area (WCA) As Restoration Strategies projects are implemented, TP reductions are anticipated Downstream Monitoring will assist in tracking progress Partial Water Year (WY) 2015 TP gradients are similar to previous years 29
