The Project

EGGI was hired to assess the potential to develop a source of irrigation water for the Virginia State Golf Association property in Powhatan and Chesterfield Counties, Virginia.  The average well yield in the local area was only 5 gallons per minute.

EGGI used remote sensing, geologic mapping, bedrock fracture mapping, and recharge analysis to delineate four zones within the project site where the prospects for developing large volumes of water appeared highest.  Then, within these zones, EGGI conducted intensive geophysical surveying to confirm the existence of structural targets identified by the earlier work, refine their location, and select for test drilling those sites that exhibited the best combination of technical characteristics.  EGGI conducted magnetometer and VLF-EM surveys along ten miles of survey lines, which were laid out in dense grids.  Nine test well sites were identified.

Status/Results:

The test well drilling program ultimately produced two production wells with combined air-lift yield equivalent to more than one million gallons per day.  The two wells represent the highest-yielding bedrock wells ever drilled in the County.
