25
Terrorism in Water and Wastewater
26
Candidate Biological Agents

• Bacteria
• Viruses
• Biotoxins
• Additional Agents of Concern
• Model Microorganisms

27
Possible Contamination Scenarios

• Complete System Contamination
• Raw Water Source
• Treatment Plant
• Storage Facility
• Localized Contamination

28
Once a threat is received or contamination is
suspected

• What do we measure ?
• How many samples do we take ?
• How much water do we take per sample ?

29
Now What ????

• Once a Threat is Received or an Abnormal
  Observation occurs in the Monitoring System and
  is Verified, the Following Screening Methodology
  is Implemented

30
Public Health Security and Bioterrorism
Preparedness and Response Act of 2002

• Public Law No. 107-188 (June 2002)
• Began as H.R. 3448

31
Vulnerability Assessment

• A Vulnerability Assessment is a systematic
  analysis used to determine the malevolent risks
  posed to the operations of water supply,
  treatment and distribution systems.

32
USEPA Mandated VA Components

• Determine Water System Objectives
• Prioritize Adverse Events/Consequences Affecting
  the Water System and the Surrounding Community
• Define How the Malevolent Acts Might be Conducted
• Assessment of Probability
• Systematic Site Characterization
• Develop a Performance-Based Vulnerability
  Assessment
• Determine the Critical Assets
• Determine System Vulnerabilities and a
  Prioritized Plan for Security Upgrades

33
Vulnerability Assessment Timeline

• March 31, 2003, for all (large) water systems
  serving a population of 100,000 or more
• December 31, 2003, for all (medium-sized) water
  systems serving a population of 50,000 or more
  but less than 100,000 and
• June 30, 2004, for all (small) water systems
  serving a population greater than 3,300 but less
  than 50,000.

34
Very Small Systems

• Funding will be provided to very small water
  systems to perform the vulnerability assessments
  and emergency response plans. The U.S. EPA Water
  Protection Task Force will provide guidance to
  community water systems serving a population of
  less than 3,300 people (very small systems) on
  how to conduct vulnerability assessments and
  prepare emergency response plans.

35
Unresolved Issues

• How secure is secure (How Much is Enough) ?
• How do we use the appropriated funds wisely ?
• How do water utilities share sensitive
  information with each other ?
• Determining the relative importance of the
  following
• Quantity of water for fire protection.
• Acceptable water quality.
• How do we protect public health ?

36

37
What is Green Construction ?

• The deliberate incorporation of sustainable
  development and environmentally acceptable
  principles into new construction and
  infrastructure rehabilitation.

38
