Groundwater can be impacted by industrial or naturally occurring contaminants, and M&A has decades of experience characterizing this contamination at federal- and state-led Superfund sites, mines, and other locations. Our expertise includes working with arsenic, chromium, industrial solvents, PFCs, 1,4-dioxane, fuel hydrocarbons, coal combustion residuals, metals, perchlorate, and other contaminants. M&A professionals specialize in developing models to project contaminant behavior in complex hydrogeologic environments. Our work has supported successful negotiations between potentially responsible parties and regulatory agencies.
- Characterizing the occurrence and nature of contaminants
- Characterizing vadose zone and aquifer conditions
- Identifying and evaluating impacts from contaminant source areas
- Sampling groundwater, soil vapor, and soil in accordance with regulatory protocols
- Assessing vapor intrusion risks
- Using groundwater flow and transport models to project contaminant migration, attenuation, and cleanup in soil and groundwater
- Preparing plans–such as monitoring, quality assurance, and health and safety–and reports–such as preliminary investigation, site characterization, and remedial investigation–to meet regulatory requirements
