Several management tools are needed to guide state response to incidents of ground-water pollution because of the large number of incidents at which State response actions may need to be performed. Two primary management tools are described in this document. These management tools are: General response procedures - guidance as to how and when state actions are initiated in response to incidents of groundwater pollution concern; and Incident tracking procedures - An Information Management System to facilitate the recording, tracking and distribution of information on the status of each contamination incident.
