Water Resource Evaluation

MMA has provided water resource evaluation for numerous industrial and government clients.  Specifically, MMA has provided ground-water basin analysis, ground-water modeling, ground-water supply, wellhead protection evaluation, surface-water/ground-water interaction assessment, and field investigations.  MMA believes that ground-water resource evaluation requires careful review of all contributors to water budgets and an understanding of all basic data collected.

Contaminant Hydrogeology

MMA has completed analyses of contaminant hydrogeology for numerous clients across the United States.  Investigations included chemical fate-and -transport, contaminant travel time calculations, contaminant plume history matching, remedial alternative evaluations, contaminant plume allocation, and natural attenuation assessment. These evaluations have been completed for a wide variety of complex hydrogeologic conditions including fractured and faulted bedrock and heterogeneous subsurface materials.

Mining Hydrogeology and Impact Assessment

Since its inception, MMA has provided hydrogeologic consulting services to mining and related industries. MMA analyses have been used to establish  ground-water extraction rates for mines, minimize the potential for depletion from surface-water bodies, and support negotiations with state and federal regulators.

Expert Technical and Negotiation Support

MMA's principals are experienced in providing expert opinion on hydrogeologic conditions and ground-water modeling in expert reports, depositions, and trials.  They have special expertise in cases that involve ground-water contamination-related insurance claims, contaminant plume allocation issues, remedial action disputes, and water-resource allocation.  MMA's first-hand experience in the development and application of ground-water modeling has provided legal clients with both expert review of existing ground-water models and development of scientifically defensible ground-water models for application to real-world problems.
