Regulatory Negotiations

Client: Zidell Marine Corporation

Location: Portland, OR

MFA characterized sediment and pore water, and evaluated chemical concentrations; bioassay results; and ambient, background conditions to assess risk to human health and the environment and identify the optimal remedy. MFA led the negotiations that resulted in the selection of a realistic cap boundary that was based on an area-weighted approach and reductions in risk provided by a variety of capping scenarios.
