1. Design of Water Quality Monitoring Dragline in operation along FL 62 nr Ft Green Springs

4. How do you find trends in water quality, without historic data?

5. Assessment of Effects of Differing Watershed Land Uses on Water Quality based on Comparisons of Six Stream/River Systems: • St. Mary’s River- Control • Myakka River-Large Agricultural Impact • Horse Creek – Limited Impacts of Agriculture & Mining • Payne Creek- Large Phosphate Mining Impact • Peace River at Arcadia- Combined Agricultural & Mining Impacts • S. Prong Alafia River- 60-70% Mined Basin

6. St Mary’s River- control No Trends in Water Quality over Time

7. Myakka River- Agricultural Pollution: Increasing sp. cond. & [K]

25. Water Quality in Reclaimed Wetland Streams • Hall’s Branch • Jamerson Jr. • Lizard Branch • Dogleg • Pickle • Tadpole

27. The Normal Progression by Levels of Approximation in Field Toxicity Testing: • TIER 1- Is there toxicity by standard lab. bioassays? • TIER 2- Is there toxicity for native species in situ? Are species “missing” that should be present? • TIER 3- What is the toxicity due to? • TIER 4- What is the source of the toxin(s)?

31. HCSP Needs Changes • Water quality - re-set trigger levels; add sampling sites above and below points of discharge and increase number of samples • Bio-monitoring - use full 3 tier system of bioassays on field observations, lab tests and in-situ enclosures

32. HCSP Needs Changes • The Bottom Line - Design rigorous plan for bio-monitoring prior to agreement - Convene outside panel free from conflicts of interest to design plan and oversee implementation
