Client project details

Augusta County Service Authority, VA (Blue Hole – Fishersville)

The Project

EGGI was retained to assess the potential groundwater yield from this significant karst feature for the Augusta County Service Authority (ACSA).  As part of this investigation, more than 60 domestic wells, springs, and sinkholes were monitored (water levels were measured every four hours over a period of 12 months).  A long-term pumping test was performed during the summer months to assess the sustainable yield and groundwater quality derived from this bedrock aquifer.

Status/Results:

The results of this investigation demonstrated that the safe yield of this groundwater source exceeded 700 gpm (1 MGD).  It was determined that the permanent groundwater withdrawal of such a yield would not significantly increase the risk of sinkhole formation and/or groundwater contamination.  This water supply source is being considered for inclusion into the overall ACSA water distribution system.
