  • Dilution: Reducing the concentration of a contaminant by adding large quantities of clean water or other suitable diluents. This is effective only for certain types of contaminants and under specific conditions.
  • In-situ Treatment: Treating contaminants within the affected area without removing them, using techniques like bioremediation (using microorganisms to break down pollutants).

Remediation Techniques: These focus on cleaning up and restoring the affected area. Methods include:

  • Excavation and Removal: Digging up and removing contaminated soil or other materials for off-site treatment or disposal.
  • Soil Washing: Removing contaminants from soil using water or other solvents.
  • Thermal Desorption: Heating contaminated soil to vaporize volatile contaminants, which are then collected and treated.
  • Bioremediation: Using microorganisms to break down contaminants in soil or water.
  • Phytoremediation: Using plants to absorb and remove contaminants from soil or water.

Chapter 2: Models

Effective EERU operations rely on well-defined models for response and management. These models guide decision-making during an emergency and ensure a coordinated approach. Key models include:

  • Incident Command System (ICS): A standardized management system used for managing emergency response activities, ensuring clear lines of authority and communication. This is crucial for coordinating multiple agencies and resources.
  • Emergency Response Planning (ERP): Developing pre-incident plans that outline procedures for specific types of environmental emergencies. These plans detail roles, responsibilities, and communication protocols.
  • Consequence Modeling: Using computer simulations to predict the potential impact of an environmental emergency, aiding in resource allocation and response strategy development.
  • Risk Assessment Models: Identifying and evaluating potential environmental risks associated with various activities or locations. This information is crucial for preventative measures and emergency preparedness.
