 GZA provides geologic, hydrogeologic, environmental and engineering services to a variety of mining industries. Our clients are involved with the extraction of metallic minerals, non-metallic minerals, and aggregate using surface and underground mining methods. Our services also includes work at former mining sites where environmental concerns associated with storage tanks, contaminated fill and groundwater were addressed.
GZA provides planning, implementation, and documentation of scientific and engineering services and support to our clients in public and private presentations to local, state, and national regulatory, political and quasi-public and private public interest groups. These presentations range from informal tours and oral presentations to formal presentations at public meetings and expert testimony at hearings and trials.
Geologic services include remote and field research and exploratory investigations to characterize local geology, structural geology and hydrogeology; collect and evaluate data to support reserve estimates; development of conceptual and computer hydrogeologic models to describe and predict groundwater interactions; and mine planning. Field activities include detailed soil and rock core logging, in-situ testing of hydrogeologic parameters, surface and subsurface geophysical investigations and surface and subsurface field mapping of geologic formations and structural features.
Environmental services include due diligence associated with property transactions (site assessments) and business operations (environmental and health and safety compliance), permit compliance assessment and corrective action, development of permit applications, and investigation and remediation of waste and contaminated materials.
Environmental services also include a variety of matters associated with surface water and wetlands. Surface water matters addressed by GZA include NPDES permitting, stream relocation, organism characterizations and associated permitting. Wetland matters include delineation, impact assessments, restoration and mitigation, controlled surgical abatement and permitting.
Engineering services stand-alone or support our geologic and environmental work. These services include investigation, evaluation, design and development of plans and specifications for geotechnical engineering of support structures and surface water design and control structures; tailings dam assessment and design; in-situ testing and monitoring of soil and rock stability; vibration monitoring; development of operation and maintenance procedures for new and/or expanded mine operations; and geotechnical testing of soil and bedrock samples in our laboratory.
Our variety of staff provides unique opportunities for us to combine our geologic and environmental expertise with engineering services to identify and characterize issues and develop sound engineering solutions to address most related issues facing our mining clients. Examples include new mine development, mine reclamation, relocating wetlands, groundwater infiltration control, and surface water – groundwater interactions. |
