What is “groundwater not in an aquifer?
A. “Groundwater not in an aquifer” is water that exists in a saturated state below the ground surface but is of insufficient quantity to act as a transport mechanism or a pathway to affect a potential receptor in its natural state. Subsurface investigative or geophysical activities, supplemented by information obtained from published reports and/or investigations at nearby facilities, should be performed to document that the stated condition exists, and that there isnt any hydraulic communication with other aquifer(s), exposure pathways or receptors. (NOTE: Permeable backfill, e.g., in buried utility trenches, may create a preferential pathway that could act as a transport mechanism to affect a receptor.) Conditions may exist in certain areas of the state where the groundwater may be used as a private potable water supply by the use of “crock wells.” Contact should be made with the local health department to identify these areas.
