NCR - Major Water Supply Sources
Patuxent10.2 BG
Occoquan 8 BG
The NCR uses about 500 million gallons per day (mgd)
Annual avg. Potomac River flow is 7000 mgd
Primary reservoir Drought reservoir

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

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

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

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)

NCR Water Security Monitoring – Current and Proposed Sites
11
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
13
Intelligent Aquatic Biomonitoring System (iABS)
14
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
