3. 3 Washington Region Water Suppliers and Distributors

4. 4 NCR - Major Water Supply Sources Patuxent 10.2 BG Occoquan 8 BG The NCR uses about 500 million gallons per day (mgd) Annual avg. Potomac River flow is 7000 mgd Primary reservoirDrought reservoir Potomac River 7BGD

5. 5 Schematic of NCR Water Supply System

6. 6 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

7. 7 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

8. 8 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

9. 9 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)

10. 10 NCR Water Security Monitoring – Current and Proposed Sites

11. 11 Aquatic Biomonitoring for Rapid, Continuous Toxicity Assessment

12. 12 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

13. 13 Intelligent Aquatic Biomonitoring System (iABS)

14. 14 Monitor detects toxicity by sensing changes in fish behavior or physiological conditions

30. 30 Air Compressor - TOC

31. 31 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

32. 32 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
