1. How do pollutants compare to various guidelines?
2. Can pollutant changes be linked to changing inputs?
1. What should cleanup targets be?
2. Which pollutants accumulate faster than they can be degraded?

4. What is the relative magnitude of pollutant inputs from different pathways?
4. Can data from a few high intensity sites be projected to other watersheds?
3. Which factors influence effects of specific pollutants on biota?
3. Which pollutants bioaccumulate?

Lessons, continued• Management actions produce
results• Estuary and watershed processes
affect beneficial use restoration• Emerging pollutants require
increased attention

• Traditional: “Fix” problems after they have become “emergencies” in the public eye – TMDLs Forever!
• New: Anticipate problems through surveillance, develop predictive recovery models, emphasize risk assessment and problem prevention

Next Steps
• Systematic look at efficiencies• Modeling the system is now
possible!
