Environmental Engineers
  • We are NOT Tree Huggers !!!!!!!!!!!
  • We are NOT Environmentalists

5
Environmental Engineers
  • Use
  • Fundamental Engineering Principles
  • to Solve
  • Environmental Problems

6
Environmental Engineering
  • Generally, The Solution to Pollution is Dilution

7
Environmental Engineering Defined
  • THE APPLICATION OF ENGINEERING PRINCIPLES AND
    PRACTICES FOR
  • ENVIRONMENTAL QUALITY CONTROL,
  • WITH EMPHASIS ON AIR, LAND, AND WATER RESOURCES
    AND THE DESIGN, CONSTRUCTION, OPERATION, AND
    MAINTENANCE OF SYSTEMS AND PROCESSES FOR
    PROTECTING AND IMPROVING THE QUALITY OF LIFE AND
    THE ENVIRONMENT.

15
Infrastructure
16
How Many Infrastructure Components ???
17
Civil EngineeringInfrastructure Components
  • Buildings
  • Bridges
  • Highways
  • Water and Wastewater Treatment Plants
  • Wastewater Collection Systems
  • Water Distribution Systems
  • Electric Power Generation and Distribution
  • Natural Gas Storage and Distribution

Professional Implications
  • Has September 11 Changed Civil and Environmental
    Engineering ???

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
Green ConstructionandSustainable Development
37
What is Green Construction ?
  • The deliberate incorporation of sustainable
    development and environmentally acceptable
    principles into new construction and
    infrastructure rehabilitation.

38
CEE Green Construction Program Goals
  • Produce students who will understand, appreciate
    and advocate principles of sustainable
    development and green construction.
  • Promote environmentally responsible practices in
    the building industry.
