  1. National Water Quality Monitoring Network for U.S. Coastal Waters and Their Tributaries Briefing For The Advisory Committee on Water Information September 14, 2005

  2. Origins of the Project An Ocean Blueprint for the 21st Century Final Report of the U.S. Commission on Ocean Policy The US Ocean Action Plan The Administration’s Response Both called for the creation of a National Water Quality Monitoring Network

  3. National Water Quality Monitoring Network • Three Ocean Commission Recommendations: • Develop network that coordinates and expands • existing efforts • The network should include coverage in both the coastal and upland areas that affect them, and be linked to the Integrated Ocean Observing System • Network must have clear goals, specify core variables, and an appropriate sampling framework, and be periodically reviewed and updated.

  4. Industry Local 2% 7% Federal 40% State & Tribal 28% Academia 23%

  5. Approach to the Design • Design the network using criteria derived from: • Specified goals and objectives • Management questions • Compare design with existing monitoring efforts • Then: • Include • Improve • Define as external to the Network

  6. Goals of the National Water Quality Monitoring Network • Integrate, coordinate, and as necessary enhance water quality monitoring efforts needed to make informed management decisions for sustainable use of aquatic resources. • Communicate the availability of quality assured data, and disseminate information products relevant to national, regional and local needs.

  7. Objectives of the National Water Quality Monitoring Network • Define status and trends of key water quality parameters and conditions on a nationwide basis. • Provide data relevant to determining whether goals, standards, and resource management objectives are being met, thus contributing to sustainable and beneficial use of coastal and inland water resources. • Provide data to identify and rank existing and emerging problems to help target more intensive monitoring, preventive actions, or remediation.

  8. Objectives of the National Water Quality Monitoring Network 4. Provide data to support and define coastal oceanographic and hydrologic research, including influences of freshwater inflows. 5. Provide quality-assured data for use in the preparation of interpretive reports and educational materials.

  9. IOOS Regions

  10. What the Network Will Provide A framework • That links the upland to the coasts and ocean • Provides national coverage • That can support local needs: • Finer temporal or geographic scale • Additional indicators • That has data standards • That has provisions for data management and access

  11. What the Network Will NOT Cover • Provide data on all water resources • Small rivers • Lakes and reservoirs • Local aquifers • Replace State Clean Water Act use attainment monitoring • 305b and 303d • Compliance monitoring

  12. The Design • Resource compartments • Specific stressors • Purpose • Flow and Loads • Condition assessments • Approach • Station locations • Constituents • Frequency • Data Considerations • Metadata requirements • Data management • Data access • Implementation • Institutional considerations

  13. Water Resource Compartments • For each IOOS Region: • Major Rivers • Estuaries • State & Territorial Waters • Coastal Oceans to the Edge of the EEZ • Wetlands • Ground water • Recreational beaches • Atmospheric deposition

  14. Stressors Affecting Resources • Oxygen depletion • Nutrient enrichment • Toxic contamination • Sedimentation • Harmful algal blooms • Habitat degradation • Invasions by exotic species • Pathogens (indicator bacteria)

  15. General Approach • Conduct routine sampling on a network of fixed sites • Perform probabilistic sampling on the Nation’s largest rivers and coastal waters • Ensure that 90% of flow to each IOOS Region is sampled • Utilize existing networks and methods • Conduct regular assessments of data • Adaptive parametric coverage and sampling schedules

  16. River Monitoring Sites Explanation Active streamgage Activewater-qualitysite

  17. Adequacy of existing streamgage network for meeting Network design goal in Chesapeake Bay watershed.

  18. River Data Collection • Continuous streamflow • Water-quality samples • 12 – 15 per year • Nutrients, suspended sediment, metals, pesticides, and other site-specific constituents • Sample over full of range of flows • Biology once per year (index period) • Bottom sediments every 5 years • Utilize tissue contaminant information from BEST network

  19. Representative Station Network • Determine conditions on major rivers of the Nation • Sample goal: 90% of the flow to each IOOS Region • 50 representative sites per IOOS Region • Five year interval • Same analyses as for each targeted site • Build on existing programs (BEST, EPA Great Rivers, ORSANCO, etc.)

  20. Stream segments for which mean flow is greater than 5,000 cfs or drainage area is greater than 25,000 sq mi.

  21. General Approach to Sampling Estuaries • Define extent of the estuarine resource • Link to riverine sampling • Work within IOOS regions, state boundaries • Cover 138 NOAA Listed estuaries • Choose and distribute probability – based sampling sites • Establish the monitoring schedule and arrange for it – through existing programs

  22. Estuary Monitoring Sites Louisiana Example • Sampling Estuaries

  23. General Approach for Sampling State Waters and the EEZ • Define extent of these waters using NOAA definitions • Link to IOOS regions • Choose and distribute sampling sites • For many physical parameters, use remotely sensed data in combination with fixed sites • Establish the monitoring schedule and arrange for it

  24. Monitoring the Coastal Ocean Sites randomly placed inside the contiguous zone EEZ Waters to be sampled remotely Contiguous Zone and EEZ Waters In IOOS Regions

  25. Inventory of Existing Monitoring • Identify existing Federal programs • Identify state and local programs in case study areas • Determine whether data in these programs meet objective criteria • Those that do meet criteria are candidates for inclusion in NMN • Track reasons for exclusion—high priority for action

  26. Primary Criteria Used to Screen Existing Networks • On-going programs • Data available electronically • Database searchable using location and constituents as search criteria • QA/QC • Metadata available electronically and of sufficient quality

  27. Metadata documentation is expected using long-standing Council/ACWI data element format Results and metadata storage to be electronic Access to be assured via web service portals via XML Data Issues

  28. Progress To Date • The Design is set – • Detailing the contents • Geography • Parameter lists • Metadata needs established • Data Management & Access • Web Services • Network of Networks • DMAC Compatible • The Issue of Institutional Arrangements being framed

  29. Progress To Date • We are addressing: • Common definitions of environmental compartments • Common information goals • The use of different design approaches • Common parameter specifications • Sample timing • We are starting to address: • Metadata standards • Field data Collection & handling • Analytic procedures • Data storage, and data access practices

  30. Network Milestones • Council Meeting: Nov 1-3, 2005 • Draft Report by the Holidays • Final report: Mid-Jan 2006 • Nat’l. Monitoring Conf. May 7-11, 2006
