6. SUMMARY FIRST RMP ANNUAL MEETING “IT’S BEEN A LOVE FEST” (Steve Ritchey: SF RWQCB)

7. 15 YEARS LATER SF BAY : NATIONAL MODEL (Sañudo-Wilhelmy et al., 2004. Environmental Science & Technology)

8. THE PROBLEM - ELSEWHERE Literature Survey metals in US estuaries 1975-2002 Results only 83 published articles no data ~ 1/2 US estuaries Only long term metal studies SF Bay Most studies in other estuaries being done by RMP alumni Sañudo-Wilhelmy et al., 2004

13. OTHER PROBLEMS WITH SF BAY Physical Complexity Hydrologic Complexity

14. RMP DATA QUANTIFY TEMPORAL CHANGES Ag & Pb in the South Bay (1989-2000) Dissolved Ag: 40% decline Dissolved Pb: no decline Total Ag: 70% decline Total Pb: 40% decline Squire et al., 2002. ES&T

15. RMP DATA ENABLE PROJECTIONS Cooke et al., URS & Monismith et al., Stanford Schubel et al., 2003

16. RMP DATA MODEL LIMITATIONS Small data set Limited spatial coverage Assumptions of constancy in an inconstant world Flegal et al., 1991 It is safer to interpolate than extrapolate It is safer to interpolate than extrapolate

17. RMP DATA FOSTER COLLABORATIONS & INNOVATIONS MEANINGFUL WATER QUALITY CRITERIA

18. EMERGING CONCERNS Population growth water demands contaminant inputs Urbanization surface runoff Negative sediment budget contaminant re-exposure Global warming reduced fresh water flows reduced sediment flows Sewall and Sloan, 2004, JGR
