  1. NCR Water Security Monitoring Network In the NCR Presented by Jim Shell Principal Water Resources Planner Metropolitan Washington Council of Governments Department of Environmental Programs Presented to Regional Monitoring Committee October 17, 2006

  2. Washington Region Water Suppliers and Distributors

  3. NCR - Major Water Supply Sources The NCR uses about 500 million gallons per day (mgd) Annual avg. Potomac River flow is 7000 mgd Patuxent 10.2 BG Occoquan 8 BG Potomac River 7BGD Potomac River 7BGD Primary reservoir Drought reservoir

  4. Schematic of NCR Water Supply System

  5. Where does the water go? • Public water systems in the NCR serve about 5 million customers, including: • approximately 670 government-owned and leased regional buildings; • prominent national “icon facilities” such as: • The U.S. Capitol Complex • The White House • The Pentagon • The world-class museums of the Smithsonian Institution • The memorials along Washington’s Mall

  6. Water – Critical Infrastructure • Water is recognized as critical infrastructure in Presidential directives HSPD-7, 9, and 10, in the National Infrastructure Protection Plan, and in the Bioterrorism Act of 2002

  7. A Comprehensive Approach to the National Capital Region’s Water Security • Coordinate Water Security Work Group • Monitoring (biological/chemical) • Modeling(RiverSpill/ PipelineNet) • Redundancy(Interconnections/Power) • Operation Plans/BMP’s (Fire, Hospitals, Sanitation, Potable Water) • Training and Exercises

  8. NCR’s Water Security Program - Monitoring • NCR Goal – early warning system for contaminants at all water intakes, all water treatment plant exits, high population areas, critical buildings • 17 monitors (biological and chemical) installed or being installed in Potomac (raw water) and in distribution systems (treated water) – operated by water utilities • Regional communication network, • Regional protocols • Major funding through DHS-UASI FY 04 grant • Additional funding – • USEPA Region III, STAG • FY 06 UASI grant (Maintenance/Radiation Monitors)

  9. NCR Water Security Monitoring – Current and Proposed Sites

  10. Aquatic Biomonitoring for Rapid, Continuous Toxicity Assessment

  11. Problem Statement • Chemical monitors alone are not adequate • Aquatic biomonitor provide advantages • Toxic effects monitoring • Sensitive to wide spectrum of industrial and agricultural chemicals (metals, pesticides, organic solvents) • Continuous (24/7), real-time monitoring • Low maintenance costs

  12. Intelligent Aquatic Biomonitoring System (iABS)

  13. Monitor detects toxicity by sensing changes in fish behavior or physiological conditions

  14. Biomonitoring Operation

  15. YSI Multiprobe Recirculating Tank Auto Sampler

  16. Fish Biomonitor

  17. Carbon Electrodes Fish Ventilatory Chambers

  18. Dechlorination Unit

  19. Chiller

  20. Central Fish Aquaculture/Stocking Operation

  21. Example Field Deployments

  22. Chemical Water Quality Monitoring System

  23. Chemical Water Quality Monitoring System

  24. Monitoring Panel Turbidity pH Conductivity Chlorine TOC Turbidity

  25. Event Monitor Trigger System

  26. Event Monitor Trigger SystemMain Screen

  27. Automated Sampler

  28. Air Compressor - TOC

  29. Expanded Water Security Network: Radiation Monitoring • Funded under an FY 06 DHS UASI grant • Expands and enhances the existing water security monitoring network in the NCR • Will be install and operated at 4 locations in the NCR • Near Intakes and critical distribution sites

  30. Radiation Monitoring (contd.) • Real-time, inline, and continuous 24/7 monitoring • Detects alpha, beta, gamma-emitting radio nuclides • Monitors drinking water for any and all radiation contaminants • Measures, records and alarms based on total microCuries per minute

  31. For further information • Metropolitan Washington Council of Governments • Stuart A. Freudberg • Director, Environmental Programs • 202-962-3340; sfreudberg@mwcog.org • Jim Shell • Principal Water Resources Planner • 202-962-3342; jshell@mwcog.org • Steven Bieber • Technical Manager, Water Resources Programs • 202-962-3219; sbieber@mwcog.org
