Name | ENVIRONMENTAL STRESSOR |
Type | Independent |
Definition |
Purpose: Incident sounds like a bad thing and that's probably what we have in mind here, although that may be more myopia than necessity... The impact incident may be an actual occurrence of a hazard. Observation is as good a term as occurrence. Says there is something going on at a particular place and time that has already been identified within EPA as an environmental hazard. Would look across incidents to spot chronic incidents.
