Types of RA activities related to Water Quality Data Services - simplifying access to data for users Observations, including support for partners Plume Tracking Customized Products
Beach Water Quality Assessment and Modeling Activities Issue: Exposure to beach swimming waters with elevated bacterial levels is a public health concern. Goal: Develop and implement scientifically-justified decision-support tools to for accurate and defensible preemptive advisory issuance decisions. Process: 1.) Data integration 3.) Model validation 4.) Operational decision-support tool 2.) Model development Who is doing it: Related work is taking place within 6 of the RAs.
Drinking Water Quality:Huron Erie Corridor Waterways Forecast System (HECWFS) • Goal: • Reduce health risks and costs associated with pollutant spills in the Lake Huron to Lake Erie Corridor • Major Elements: • Link 2d model for corridor to NOAA Great Lakes Forecasting System • Generate 3d public domain model • Use 3d model to support water intake risk assessment work
Water Quality and Ecosystems • Buoys: Capture high resolution temporal features • Unraveled controls of light penetration in Great Bay Estuary, NH helping protect critical eelgrass habitat through developing Nutrient Criteria DO light Chl & TSM nutrients • Unraveled causes and help predict low DO in the Long Island Sound • Gliders: Capture spatial features • DO Part of NJ water quality monitoring NJDEP, EPA, Rutgers, MARACOOS

Discussion Questions • There are successes (in new technology and observation capabilities, data integration and interoperability, scientific analysis and modeling and decision support tools) around the country – at the regional and national levels. How do we transform these successes into a sustained national effort? What’s working that can be expanded right now? What are the gaps/challenges that is preventing a national effort. • 2. Data management provides a vehicle for the multitude of WQ providers to share data. How do we continue the progress made to date? How do we fund data management efforts? How to engage the broader interagency community and the larger community?
