Where: A hard rock quarry in northeastern Maryland
SECI recently completed a Hydrogeologic investigation for a hard rock quarry in northeastern Maryland. The investigation was designed to model the future groundwater withdrawal necessary to keep the quarry dewatered. Stream flow measurements, a stream water surface profile, water level readings in onsite wells and the quarry sump were used to calibrate the model run using Groundwater Vistas modeling software.
