  1. Presentation to Stakeholders for the Caloosahatchee Estuary excessive nitrogen pollution issue • Introductions • Background information on the Caloosahatchee River/Estuary • Environmental/Health Concerns with elevated nitrogen levels • Regulations, laws and policies governing Nitrogen pollution in our waterways • Nitrogen reduction plan and key players involved • Community/Environmental involvement

  2. Introductions

  3. Background of Caloosahatchee Estuary • The Caloosahatchee Estuary is fed by the Caloosahatchee River, Lake Okeechobee and the Kissimmee River • Here is a small presentation on the water flow and how it makes it way to the Caloosahatchee Estuary as well as some of the challenges and steps we have taken to reduce the nitrogen levels along the way (1) • http://www.sfwmd.gov/portal/page/portal/xweb%20protecting%20and%20restoring/protecting%20and%20restoring%20ecosystems#monitor

  4. Background of Caloosahatchee River/Estuary • Here is a ten year sampling period for the Caloosahatchee River. This chart documents the nitrogen content in the river during a ten year period (2)

  5. Background of Caloosahatchee River/Estuary • Here is a ten year sampling period for the Caloosahatchee. This chart documents the dissolved Oxygen (DO) in the river during a ten year period (3)

  6. Land uses of the Caloosahatchee Estuary (7)

  7. Environmental/Health Concerns from Excessive Nitrogen Pollution • Excessive nitrogen pollution in the water can lead to • Excessive algae growth overstimulation of aquatic plants which can use up dissolved oxygen • Excessive algae can block water intakes, use up dissolved oxygen which can cause fish kills and make some waterways impassible by boats if the algae is thick enough • In drinking water excessive nitrogen can cause “blue baby syndrome” in infants that are younger than four months old and it can also negatively impact young livestock as well (4)

  8. Regulations, Laws and Policies related to Nitrogen Pollution in water • The State complies with Section 303 (d) of the Clean Water Act, which directs each state to develop Total Maximum Daily Loads (TMDLs) for each water quality limited segment reported (5) • The state of Florida has enacted legislation (403.067) which provides a framework for how TMDLs will be developed in Florida • The state also has the Surface Water Quality Standards - Chapter 62-302 that we are required to meet as well as the impaired water rules – Chapter 62-302 • We must also create and adhere to a Basin Management Action Plan as well • We also have the Caloosahatchee River Watershed Protection Program as well which details out BMP for enactment
