PERIOD OF RECORD - July 1953, April 1969 to current year. Unpublished record available July 1953 in files of the Virginia Department of Environmental Quality - Water Division.

REMARKS - Well is located in Elbrook Formation of Middle to Upper Cambrian age. Lowest recorded water level, 7.39 ft, is a result of the Mexico earthquake of Sept. 19, 1985, but is not shown as the minimum of record since it is an earthquake affected measurement. Prior to May 1, 1990, brief periods when water flowed over top of casing. Sharp fluctuation in water levels often result of seismic actvity.
