SFEI LOOKING BACK : LOOKING FORWARD

The RMP has always been composed of a diverse (odd ?) set of individuals


SCIENTISTS


ENGINEERS


INDUSTRY


ENVIRONMENTALISTS


SUMMARY FIRST RMP ANNUAL MEETING“IT’S BEEN A LOVE FEST”

(Steve Ritchey: SF RWQCB)


15 YEARS LATERSF BAY : NATIONAL MODEL

(Sañudo-Wilhelmy et al., 2004. Environmental Science & Technology)


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


RMP ALUMNI * CONDUCTING ESTUARINE STUDIES ELSEWHERE

East Coast:

Sergio Sañudo *Stony Brook

Mark WellsMaine

Greg Cutter *ODU

John DonatODU

Gulf Coast:

Gary Gill *Texas A&M

Bill LandingFlorida State

Far East Coast:

Kuria Ndung’u *Sweden

* incomplete listing

* still involved in SF Bay-Delta studies


RMP ALUMNI * REGULATING ESTUARINE STUDIES

Priya GanguliSF RWQCB

Peter KozelkaUS EPA

Jon PhinneyNOAA

Ignacio RiveraUS Navy

Doug StedingSupreme Court*

* incomplete listing

* circa 2010


THE PROBLEM IN SF BAY150 YEARS OF POLLUTION 15 YEARS OF RMP DATA*

Gold Rush

Mercury Mines

Golden Gate

Red Lead

Silver Estuary

Industrial Discharges

Urban Estuary

Periodic Table

* prenascent RMP data collection began in 1989


MERCURY IN SF BAY

SFEI Summary Time Series Data


OTHER PROBLEMS WITH SF BAY

Physical Complexity Hydrologic Complexity


RMP DATA QUANTIFY TEMPORAL CHANGESAg & 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


RMP DATA ENABLE PROJECTIONS

Cooke et al., URS & Monismith et al., Stanford

Schubel et al., 2003


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


RMP DATA FOSTER COLLABORATIONS & INNOVATIONSMEANINGFUL WATER QUALITY CRITERIA


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
