The U.S. Environmental Protection Agency (EPA) is releasing two software tools for risk assessment and consequence analysis:
The release of VSAT and WHEAT will provide drinking water, wastewater, and combined utilities of all sizes with the capability to assess, plan for, and better respond to human-caused threats and natural disasters.
VSAT is an interactive desktop software tool that employs a proven methodology to enable users to perform customized risk assessments. The upgraded tool not only evaluates human-caused threats but has a new feature that allows users to assess four different natural disaster scenarios: hurricanes, tornadoes, floods, and earthquakes. VSAT has the flexibility for the user to assess other types of natural disasters as well.
WHEAT is an intuitive desktop software tool that assists drinking water utility owners and operators in quantifying public health impacts, utility financial costs, and regional economic impacts of an accidental or adverse event. Currently, WHEAT generates consequence results based on two scenarios for drinking water utilities: 1) release of a hazardous gas and 2) loss of operating assets. There are future plans to develop similar wastewater utility modules.
The benefits to drinking water and wastewater utilities using these tools are the following:
The VSAT and WHEAT tools are available for download free of charge through EPA’s website
