The RMP Mercury Strategy / Sport Fish Monitoring Update

This presentation discusses the RMP Mercury Strategy, including patterns in mercury uptake, high leverage pathways, opportunities for intervention, effects of management actions, and the effect of total mercury reductions. It also poses questions for further exploration and coordination of existing work.

Presentation Transcript

  1. The RMP Mercury Strategy / Sport Fish Monitoring Update Jay A. Davis San Francisco Estuary Institute Presented at: The RMP Mercury Coordination Meeting February 2009

  2. Origins • SF Bay pollutant enemy #1 • Profusion of mercury proposals • Tom Mumley’s idea • RMP Mercury Strategy Team • Stakeholder planning group • Key input from Regional Board • Strategy now bearing fruit

  3. Q1: Patterns in Uptake • Major focus for 2008 - 2010 • Spatial and temporal • RMP small fish • RMP S&T: sport fish, bird eggs, water, sediment • Other studies • FMP • SBMP • USGS

  4. Q2: High Leverage Pathways • Ideally follows Q1 • Some work now, greater focus after 2010 • RFP in 2007 • Two potentially very valuable but somewhat risky studies • Blum isotopes • Hintelman DGTs • Other studies • Mason WERF

  5. Q3: Opportunities for Intervention • Ideally follows Q2 • RMP focus on internal sources • Other programs on external sources, ecosystems • McKee Prop 13 Study • Drury Guadalupe • Ulrich • Siegel • Stephenson/Heim/Gill/Foe • Marvin-DiPasquale and Windham

  6. Q4: Effects of Management Actions • Management actions including remediation, restoration, etc. • Models – continual development • MeHg mass budget a start • Monitoring • Regional monitoring • Local monitoring as actions are taken

  7. Q5: Effect of Total Mercury Reductions • Not part of the 1-4 sequence • No specific studies currently planned

  8. Questions to Ponder Today • Are we making progress? • Are there better ways of answering our questions? (submit a proposal!) • Are any important elements missing? • Systematic monitoring of wetland restoration? • Can we coordinate existing work better?
