  • EPANET Multi-Species eXtension (EPANET-MSX)
    EPANET can model flow and water quality in pressurized pipe networks. With EPANET-MSX, complex chemical and biological reactions in drinking water distribution systems can be modeled
    Research question: How can I track chemical reactions and map the fate and transport of chemical species within water distribution systems?
  • Bio-Response Operational Testing and Evaluation (BOTE)
    BOTE is a multi-agency effort designed to test and evaluate biological incident response operations following an anthrax release (non-disease causing organism used).
    Drinking water quality can fluctuate daily and seasonally or when operating conditions change.  CANARY continuously analyzes water quality data at multiple sensor locations over time, and uses mathematical and statistical techniques to identify the onset of anomalous water quality incidents.
    Research question: What is the quality of water being provided via water distribution systems? Are any hazardous contaminants present in this water?
  • Life-cycle Cost Analysis Tool (LCAT)
    Risk assessment can identify the possible hazards confronting facilities if there is a release of chemical or biological agents. LCAT can find the most cost-effective way to retrofit and protect the facility.
  • Message Mapping Workshop Video
    Risk communicators use science-based tools for developing crisis communication. One important tool is message mapping. Sets of questions that might be asked by different audiences are developed. Then detailed, hierarchically organized messages are written, each supported by key information aimed at the particular audience.
  • Pathogen Information Catalog Tool (PI CAT)
    PI CAT contains  information derived from microbial dose-response assessment being used to support risk-based cleanup goals.
  • Rapid Viability PCR Protocol (RV-PCR)
    During the cleanup phase of a response to contamination with Bacillus anthracis spores, rapid viability polymerase chain reaction (RV-PCR) protocols are used to detect whether live spores remain in environmental samples.
  • Securing Buildings Against Chemical and Biological Agents Workshop Videos
    In several workshops, EPA and building professionals discussed how to prepare a building for a terrorist attack, and how to incorporate protective measures in the design and operation of a facility.  The videos contain information on securing buildings against chemical and biological agents.
  • Threat Ensemble Vulnerability Assessment-Sensor Placement Optimization Tool (TEVA-SPOT)
    TEVA-SPOT helps water utilities optimize the placement of water quality sensors in water distribution networks.

  • Incident Waste Assessment and Tonnage Estimator (I-WASTE)
    I-WASTE provides waste management information for natural disasters, terrorist attacks, and animal disease outbreaks. It was developed in order to address the "system of systems" aspects of wide-area remediation following a chemical, biological, or radiological incident.
    Research question: What type of waste would be produced during the cleanup of a chemical, biological, or radiological contamination incident? What is the proper way to safely and legally manage this waste, and what facilities can be used to assist in this management?
  • Support for Environmental Rapid Risk Assessment (SERRA)
    SERRA is an extensive collection of information about chemical, biological, or radiological agents used for managing, cleaning up, and reducing the hazards encountered after a terrorist attack. You will need to register to use the SERRA database.
