City of Jacksonville s Targeted Water Quality Monitoring Approach Melissa M. Long, PE Fall Seminar 2017
Goals and Objective Goals Identify Potential Water Quality Problem Areas Measure effectiveness of BMPs Document Pollutant Loading/trends Objective Water Quality Improvement Implementation of SWMP Procedures and practices Effective allocation of resources Cross Department Coordination
Tools Used to Evaluate Plan Existing monitoring Evaluate trends Nutrient load reductions Bacteria reductions Support ID of source causes Annual EMC Load Calculation Per WBID local annual rainfall during reporting year Draw on previous experience LSJR Nutrient BMAP Tributaries I & II Bacteria BMAP BPCP Align interlocal agreement with co-permittee Assessment Programs
Ambient Water Quality Monitoring Current Monitoring St. Johns River (Main Stem) Tributaries Nassau and Ft. George Rivers Water Pollution Complaints Special Project Interagency Cooperation
How COJ will get there Long-term Fixed Station River Sampling Revised Fixed Station Tributary Monitoring Tributary FIB BMAP I & II Monitoring BPCP Monitoring Watershed Trend Monitoring Targeted Monitoring
