A Pilot Program for Monitoring,
Stakeholder Involvement, and
Risk Communication
Relating to Mercury in Fish
in the Bay-Delta Watershed
(aka “The Fish Mercury Project”)
SFEI

CDFG
DHS/EHIB
OEHHA
Funding provided by CBDA
Presented at the
2006 Mercury Coordination Meeting
How can we minimize methylmercury exposure?
Longer Term Solution for Humans and Wildlife
• Adaptive management of water quality and
restoration (actions and monitoring)
• Tracking regional trends in biotic exposure
• Tracking local trends near restoration and cleanup
projects
Shorter Term Solution for Humans Only
• Identify high and low areas and species
• Develop consumption advice
• Communicate risk information to the public

Description
Evaluating the potential regional impacts of
habitat restoration in the Delta
Another type of index site where more
detailed investigation of temporal variation
and mercury movement through the food web
will be conducted
Evaluating the localized impacts of CBDA
habitat restoration and remediation projects on
food web mercury
Providing the data needed to support
consumption advisory development for the
CBDA ecological management units

Sampling (UC
Davis)
Biosentinel
Sampling, 2005
• Also a few
restoration sites
further up in the
watershed
• About 10,000 fish
collected in 2005
Advisory Development, Years 1 – 3
(OEHHA)
• Linked with sport fish sampling, but
primarily based on existing data
• Year 1 – south Delta, San Joaquin
River, Cosumnes River and
Mokelumne Rivers and associated
reservoirs, Feather River
• Year 2 – north Delta, Sacramento
River, Lake Shasta, other tribs and
reservoirs in the Sacramento River
watershed
• Year 3 – Tributaries, creeks, and
reservoirs in the San Joaquin River
watershed
• Advisories to be developed using an
established protocol
• Advisory development workplan will
undergo peer review
Stakeholder Involvement and Risk
Communication, Years 1 – 3 (DHS –
EHIB)
• Linked with sport fish sampling and advisory development
• Stakeholder and risk communication workplan will undergo
peer review
• Includes evaluation of effectiveness
Stakeholder Involvement, Years 1 - 3
• Fishing activity evaluation (prior to sampling
each area)
•
•
•
•
Contact county health agencies
Contact DFG wardens and other fishing experts
Site visits
Focus groups
• Needs assessments: interviews, focus groups,
surveys – focus on risk communication
Risk Communication, Years 1 - 3
• Communicate with community
leaders (fact sheets, newsletters)
• Educational materials and
activities (multi-lingual)
• Posters, cards, fact sheets
• Mini grants to CBOs
• Delta advisory sign
• Training – building local capacity
• Forum on fish contamination and
public health held in December
2005
• FMP Annual Meeting on June
13 and 14
• Joint meeting of Steering
Committee and Review Panel
(Knuth, Wiener, Bodaly, Grieb,
McCann)
• Results of 2005 sampling
• Plans for 2006 sampling
• Progress and plans: advisory
development
• Progress and plans: fishing activity
assessment, risk communication
• Annual technical report
