Volume 3; Monitoring & Assessment Branch; p 33. Fate & Effects of Contaminants Program Review, Sept 15-17, 2020 MW Program: Purpose & Mission Statement
Nationwide Pollution Monitoring Program Since 1986 – Based on collection and analysis of bivalves (oysters, mussels) and sediment - Lower 48, AK, HI, Puerto Rico
Legislative Mandate The NOAA Mussel Watch Program was established in response to a legislative mandate under Section 202 of Title II of the Marine Protection, Research, and Sanctuaries Act (MPRSA) (33 USC1442), which tasked the Secretary of Commerce to “initiate a continuous monitoring of contaminant levels in biota, sediment and the water column.”
Mission Statement To support ecosystem-based management through integrated nationwide environmental monitoring, assessment and research to describe the current status of and to detect changes in the environmental condition of our Nation’s estuarine and coastal waters Long-term Monitoring Approach & Activities
Monitoring 300 Sites nationwide Bivalves and sediment 300 legacy + 280 CECs Bivalve health (ended 2010) Biological fecal indicators
Specimen banking With NIST (ended 2005) Valuable for new contaminants and analytical techniques
Assessment of Special Events Oil spill: DWH (2010) Severe storm: Katrina (2005) Unforeseen events: WTC (2001) Great Lakes Initiative (Place-based assessment) Long-term Monitoring Approach & Data Quality Core Legacy Parameters Monitored Analytical Chemistry (QC guidelines) Data QAPP 1986 – 1999: Multi-lab 2000 – current: TDI-Brooks International 2014: In-house capabilities with NCCOS Ecotoxicology Inter-laboratory calibration exercise

Example of Ni results: At many sites, post-landfall Ni levels were elevated relatively to pre-spill values Many of these high concentration sites were located in the potentially oiled coastal area Long-term Monitoring: conclusion & Vision for the future
Conclusion Vision for the future Since 1986, MW is the longest running Bridge MW-Bioeffects – Early warning contaminants monitoring program that is with metabolomics (DNA damage) nationwide CEC focus (funding limiting factor) MWP provides unique historic trend data Increase visibility – Data portal - that is vital for evaluating: Increase visibility through partnerships The long-term trends, impacts of oil spills (internal e.g. Charleston Lab, Oxford Lab, and hurricanes OR&R; External e.g. Fed, state, tribe) Restoration & Cleanup The effectiveness of regulations that ban How to do it better? toxic chemicals Funding challenges Provides important data tool for coastal resources management Historic trends dilemma
