Projects

Since our founding in 1990, McDonald Morrissey Assocates has completed a wide variety of projects throughout the United States and internationally. Projects range in size and scope, from advisory roles to comprehensive on-site services in the areas of groundwater resource development, wellhead and source-water protection area delineation, mine dewatering, contaminant transport evaluations, groundwater remediation assessment, plume allocation, expert testimony and negotiation support, and regional groundwater flow system analysis for both industrial and government clients.

Please explore our selected projects within our service areas for more detail:

Water Resource Evaluation: MMA has provided water resource evaluation for numerous industrial and government clients. Specific services include groundwater basin analysis, groundwater modeling, groundwater supply, wellhead protection evaluation, surface-water/groundwater interaction assessment, and field investigations.

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.

Waste Management: MMA provides modeling analyses to help a range of state, municipal, federal, and corporations assess groundwater flow conditions for waste management, including landfills, superfund sites, radioactive waste disposal sites, and subsurface injection of treated wastewater.

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.
