Client project details

Bull Run Quarry (Loudoun County, VA)

The Project

EGGI was retained by the owner of a trap rock quarry to evaluate the impact of mining a deep, open-pit mine on surrounding groundwater resources. Work efforts included the identification of the most effective areas for groundwater monitoring, the installation of a bedrock monitoring well network, and the periodic sampling of several monitoring wells. EGGI compiled and analyzed the groundwater level and chemistry data.

Status/Results:

EGGI successfully developed the groundwater monitoring plan and collected several years of groundwater level and chemistry data.  These data were used by the County to assess whether the quarry activities would adversely impact local groundwater resources.  The results of this investigation indicated that the quarry activities and use of local groundwater resources for potable supply could coexist.
