Hydrogeological characterization provides the data needed to determine the nature, concentration, and distribution of contaminants that have entered the subsurface environment, contaminant transport mechanisms, and to evaluate the risk to human health and ecological receptors. By developing an thorough understanding of such factors as geochemical conditions, aquifer characteristics, contaminant properties, soil-air permeability and microbial populations, MSE is able to identify, screen and select the most effective technologies for remediation of contaminated sites and identify cost effective alternatives to remediation, where appropriate. MSE staff members have characterized subsurface hydrogeological conditions at sites impacted by a wide variety of regulated contaminants including chlorinated volatile organic compounds, metals, pesticides, wood preservatives, radioactive wastes and petroleum hydrocarbons. We utilize many types of investigative methods ranging from non-intrusive geophysical techniques to soil boring and monitoring well installation programs and pilot scale field tests. Our goal is to combine technical expertise and knowledge of regulatory standards to develop clear understanding of contaminant distribution, transport, fate and cleanup requirements, which will serve as a basis for decisions regarding further action.
