EMAP Efforts in SF Bay

• Overview of EMAP Western Pilot

• Overview of Coastal component

• Activities in SF Bay (FY 2000)

• Relationship to other SF Bay efforts

• Opportunities for collaboration

What is the EMAP Western Pilot?

• A monitoring demonstration of indicators and designs for measuring environmental progress– Probability based survey design – Multiple indicators– Unbiased estimates of conditions of ecological

resources

Scope of the Western Pilot

• 3 Resource Components– Surface Waters - Rivers and streams in 12

western States– Coastal Waters - Estuaries and near coastal

zone in 5 states– Landscapes - Landuse patterns in 12 western

States

Purpose of EMAP Western Pilot• Demonstrate the value of survey based

monitoring– apply to real problems of Regional/State interest

• Advance the science of monitoring– indicators– designs– reference conditions– assessment methods

Objectives of EMAP Western Pilot

• Estimate the condition of ecological resources (estuaries, rivers and streams, landscapes)

• Identify likely stressors to these systems

• Build State capacity for long-term monitoring

• To create an integrated comprehensive coastal monitoring program across the West Coast states to assess estuarine condition

• West Coast States: California, Oregon, Washington, Alaska, Hawaii

Objective of Coastal Component

Schedule for Coastal EMAP

• 1999 - Small Estuaries (CA, OR, WA)

• 2000 - Large Estuaries (CA, OR, WA)

• 2001 - Estuaries and Offshore (AK, HI)

• 2002 - Offshore (CA, OR, WA)

• 2003 - New Indicators and Reporting

• 2004 - Reporting

Coastal EMAP as a pilot for a Statewide Coastal Monitoring Program

• Coordination among key players involved in coastal monitoring

• Address issues of data comparability

• Deal with challenges of information management

Participating Agencies

• Federal Agencies– EPA, NOAA, USGS

• State Agencies– CDFG, SWRCB, RWQCB

• Research Groups– SFEI, SCCWRP

Priorities for Regional Monitoring Program Redesign

• Status and Trends

• Method Improvement

• Refine analyte list

• Refine mass budget models

• Develop food web model

• Bioaccumulation (trends)

• Data review

• Source evaluation and contaminant load

• Effects of contaminants

• Pesticides

• Bioavailability of contaminants in sediments
