contamination threat vs incident
Contamination Threat vs. Incident
  • Contamination threat – an indication that a contaminant may have been introduced (not confirmed).
  • Contamination incident - the confirmed presence of a harmful substance (requires a response)
module 2 contamination threat management guide14
Module 2:Contamination Threat Management Guide

Module 2 provides:

  • A framework for decision-making
  • A threat evaluation and management process
  • Descriptions of response actions
threat evaluation and management process
Threat Evaluation and Management Process
  • Evaluation of all available information to determine if contamination is:
    • ‘Possible’
    • ‘Credible’
    • ‘Confirmed’
  • Work with minimal information
  • Iterative process that is updated as more information becomes available

Players in the Threat Management Process
  • Drinking water utilities (WUERM)
  • Drinking water primacy agency
  • Public health officials
  • Emergency responders
  • Local law enforcement
  • FBI
is the threat possible
Is the Threat ‘Possible’?
  • A threat is deemed ‘possible’ if the circumstances indicate the opportunity for contamination
  • One-hour target for ‘possible’ stage
is the threat possible18
Is the Threat ‘Possible’?
  • Information available at ‘possible’ stage:
    • Details of the threat warning
  • If a threat is ‘possible’, potential response actions include:
    • Isolation and containment
    • Initiate site characterization and sampling
is the threat credible
Is the Threat ‘Credible’?
  • A threat is deemed ‘credible’ if additional information corroborates the threat
  • 2 - 8 hour target for ‘credible’ stage.
is the threat credible20
Is the Threat ‘Credible’?
  • Information available at ‘credible’ stage:
    • Site characterization results.
