Hydrogeological Services for Quarry Expansion

Hydrogeological Services for Quarry Expansion – Washington County, MD

GMA provided hydrogeological services to a mining operation located in the valley and ridge geologic province of Maryland. GMA evaluated whether the current zone of influence (ZOI) for mine dewatering wells surrounding the quarry operation would be sufficient for a proposed expansion of the quarry. GMA conducted a site inspection and we evaluated existing data to characterize the groundwater flow system in and near the quarry and the expansion area. We determined that the ZOI for the existing quarry operation was inadequate for the proposed expansion, and we delineated new ZOI boundaries. GMA provided expert testimony before the Washington County Commissioners during rezoning hearings regarding the hydrogeology and the effects of industrial mining on the area surrounding the quarry.
