U.S. EPA's Water Health & Economic Analysis Tool is a generalized, threat-neutral consequence analysis tool designed to be used by utilities to supplement their expert opinion in risk assessment methods by providing a more detailed consequence analysis. It is designed to assist drinking water and wastewater utility owners and operators in quantifying human health and economic consequences for a variety of scenarios that pose a significant risk to the water sector, including loss of one or more assets, release of a stored hazardous gas, and intentional contamination of a drinking water distribution system.
