What is a Risk Assessment? Risk is the probabilty (or likelihood) that a
harmful consequence will occur as a result of an action. Risk is a function
of hazard and exposure. For risk to occur, there must be a source of risk (hazard)
and an exposure to the hazard. Risk assessment is the process by which one attempts
to evaluate and predict the liklihood and extent of harm (in qualitative and quantitative terms)
that may result from a health or environmental hazard. A Risk assessment provides
essential information about the severity and extent of specific environmental problems for use
in EPA risk management decisions.
