u u Non-profit scientific organization u Programs: –Contaminant Monitoring and Research Program »Regional Monitoring Program »Aquatic Pesticide Monitoring Program –Regional Watershed Science Program –Regional Wetlands Monitoring Program –Biological Invasions

Regional Monitoring Program  Innovative partnership between government, dischargers, and scientists  Work closely with the Regional Board  $ 3 million/year of stable funding  Began in 1993  World class monitoring  Major change in direction beginning in 2002

RMP Objectives  Compare monitoring information to relevant water quality objectives and other guidelines  Describe patterns and trends in contaminant concentration and distribution  Describe general sources and loading of contamination to the Estuary  Measure contaminant effects on selected parts of the Estuary ecosystem  Synthesize and distribute information from a range of sources to present a more complete picture of the sources, distribution, fates, and effects of contaminants in the Estuary ecosystem

RMP Components  Water Chemistry  Aquatic Toxicity  Sediment Chemistry  Sediment Toxicity  Bivalve Bioaccumulation  Fish  Pilot Studies  Special Studies

303(d) Listed Chemicals u Draft list from 11/01 u High Priority –Mercury, PCBs u Medium –Chlordane, DDT, Dieldrin, Diazinon u Low –Selenium, Dioxins, Furans, Dioxin-like PCBs

303(d) “B” Listed Chemicals u Draft list from 11/01 –Copper –Nickel –PAHs –PBDEs –Sediment Toxicity

Conceptual Model of PCB Fate in the Bay

Predicted Long Term Trends in PCB Mass with Varying Loads

New Contaminants of Concern: Flame Retardants TetraBDEPentaBDE HexaBDE Sources: textiles, household and industrial products Use: reduces flame capacity of materials Max level: ppt (ng/L) Sacramento River water Concern: endocrine system disruption, bioaccumulation Triphenylphosphate

My Water Quality Report Card for the Bay  Getting Better  DDT, chlordane  Sloooow improvement  PCBs  Staying the Same  Hg  Getting Worse  PBDEs (?), Pyrethroids (?)
