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

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 Washingtons Mall

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
A Comprehensive Approach to the National Capital
Regions Water Security

• Coordinate Water Security Work Group
• Monitoring (biological/chemical)
• Modeling (RiverSpill/ PipelineNet)
• Redundancy (Interconnections/Power)
• Operation Plans/BMPs (Fire, Hospitals,
  Sanitation, Potable Water)
• Training and Exercises

NCRs 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)

Aquatic Biomonitoring for Rapid, Continuous
Toxicity Assessment
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

Intelligent Aquatic Biomonitoring System (iABS)

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

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
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
