Client project details

Augusta County Service Authority (Lyndhurst, VA)

The Project

The Lyndhurst Well, located in Lyndhurst, Virginia, provides the Augusta County Service Authority (ACSA) with over 760,000 gpd of potable water. In 2007 alone, 277 million gallons of groundwater were utilized from this Well to provide water for the County. EGGI was contracted by the ACSA to identify the contributing recharge area to the Lyndhurst Well; in other words, define the Wellhead Protection Area (WHPA).

As part of this effort, EGGI collected extensive background data on existing wells and contaminant threats. Integral aspects of this project included karst feature mapping, bedrock mapping, remote sensing, and geophysical surveys to characterize the local geologic setting. EGGI installed numerous monitoring wells and set up automated water level recording data loggers in the newly installed monitoring wells, existing domestic wells, and surface water sites.  All observation wells were monitored to assess where water level changes in the local bedrock aquifer occurred as a result of terminating pumping of the Lyndhurst Well for intermittent periods of time. Water samples were also collected from numerous locations and analyzed for a suite of water quality parameters, including bacteria and MPA (microparticulate analysis).

Status/Results:

The technical data collected during this study allowed EGGI to accurately delineate the 2,360-acre (3.7 square mile) WHPA and develop a strategic groundwater monitoring and protection plan, which will serve the ACSA as a useful water supply planning and protection tool for future generations.
