Impact/Purpose:
There is concern that hazardous substances released during a terrorist attack will contaminate people and the environment. However, there are few health-based guidelines for temporary building or outdoor site re-entry or for resumed use of water resources, as might be needed after a large-scale disaster. EPA is, therefore, developing health-based provisional advisory levels (PALs) for high priority hazardous chemicals and chemical warfare agents in air and drinking water. PALs are a tiered set of exposure values used to inform risk-based decision making during a response to environmental contamination involving hazardous chemicals. They are advisory levels for exposure to chemicals by the general public, including susceptible and sensitive sub-populations and are developed for the following exposures to contaminated air and water: •Acute (24 hours) •Short-term (longer than one to 30 days) •Long-term (longer than 30 days to two years).
