  1. Gated access to harbor Charlotte Harbor Environmental Center Water Quality Canal Sampling

  2. Charlotte Harbor Environmental CenterCanal Water Sampling Program • South Gulf Cove • Initiated 2009 • Five Stations sampled in canals • Quarterly samples by Benchmark technicians • Benchmark EnviroAnalytical Inc. analysis • Nitrogen, Phosphorus, Fecal Coliform bacteria • Dissolved Oxygen, pH, Salinity • Station Depth, Secchi Depth • Air/Water Temp., Wind Spd./Dir., Cloud Cover

  3. Processes Affecting Water Quality • Tides - Not important in this location due to limited access • Wind - Can cause some local currents • Circulation - No flushing of canals • Salinity - Mainly dependent on rainfall, evaporation • Temperature - Shallow canals, little vertical change • Sunlight - Plant growth • Rain and Runoff - Potential source of pollution from land • Turbidity - Vertical mixing, runoff • Boating Activity

  4. Sampling Dates Feb. 2009 May 2009 Aug. 2009 Nov. 2009 Feb. 2010 May 2010 Nov. 2010 Nov.2011 Feb. 2012 May 2012 Aug.2012 Nov. 2012 Station Locations 1 2 3 4 5

  5. Data Interpretation Methods:  Dissolved Oxygen: Fish & Wildlife Standards.  Bacteria: Public Health Standards.  Secchi: FDEP Typical Water Quality Values.  Chl & Nutrients: FL Trophic State Index.
