2 Some Simple Questions How have pollutant inputs changed? Is the ecosystem protected? Is it safe to eat the fish? Is it safe to swim?

8 Three Pivotal Studies Shift Management Attention To Runoff More pollutant mass from runoff than wastewater Regional Survey indicates that 95% of So Cal beaches meet bacterial water quality standards - Remaining 5% near flowing storm drains Epidemiology Study identifies increased swimmer illness near flowing storm drains

9 Clean Beaches Initiative Grants

11 The CWA Had an Impact Traditional pollutant inputs are much less than 40 years ago - Reduced impacts to biota The vast majority of beaches and seafood species meet standards - Some locations still require work Future issues will challenge the CWA framework - Emerging contaminants - Ocean acidification and hypoxia

13 Data from NOAA: Aloha Buoy

14 Solving Large-Scale Water Quality Threats Requires New Perspectives What is the relative impact of large-scale sources versus local sources? What new information is necessary for making decisions to adapt and protect our natural resources from large-scale sources? What management mechanisms are available to mitigate large-scale sources?
