ARM Contract Renewed with Virginia Department of Public Works

The Fairfax County, Virginia  Department of Public Works has renewed its contract with ARM Group to provide hydrogeologic consulting services for another two years.  ARM performs semi-annual sampling of over 60 wells at the County’s two landfills.  ARM performs statistical data analysis and prepares regulatory reports for the groundwater monitoring program.  In addition, because volatile organic compounds have been detected in some wells above groundwater protection standards, ARM assisted the County in preparing a permit amendment for a groundwater Corrective Action Plan which calls for injection of a hydrogen releasing compound to enhance bioremediation in the groundwater.  ARM performed the initial injections of HRC last summer and is currently conducting additional investigations using geophysical techniques and conventional drilling to prepare the plan for full-scale implementation of the proposed remedy.
