Human Health / Ecological Risk Assessment


LBG conducts sound, qualitative and quantitative human health and ecological evaluations to characterize the nature and extent of direct and indirect exposures to chemical compounds in the environment. We utilize methods and assumptions that are based on state-of-the-art science, yet offer our clients with solutions that are simple and reasonable to implement. The foundation of our risk assessments are based on a thorough and complete site characterization to determine the magnitude and extent of impacts to soil, groundwater, air, sediments, and surface water. Geologic and hydrogeologic assessments as well as fate and transport modeling, are also completed to accurately characterize risk per current and future site conditions. LBG prides itself in recognizing alternative solutions to active remediation. A successful risk assessment can eliminate the need for invasive technologies, while establishing alternative agency-approved risk-based cleanup goals.
