Dr. Teri Floyd is a professional chemist with over 20 years experience in environmental systems analysis.

Teri specializes in complex project management for sites and projects with interwoven regulatory, business, and technical challenges, often crafting creative "out-of-the-box" solutions predicated on sound science and an understanding of business and regulatory processes. Because Teri believes that creative ideas are only as good as their implementation and outcome, she works with her clients from early planning through implementation and closure. Teri uses these skills at upland and sediment sites throughout the country, primarily here in the Northwest.

Teri is particularly skilled in the management of complex environmental issues for multi-party groups. She has an exceptional ability to work with multiple parties to define project approach strategies that are robust in their attention to multiple objectives, technical detail, and scientific grounding. She is an excellent negotiator and manager, especially for those projects that must be completed against a backdrop of changing regulatory climates, client needs, or site conditions.

Over the years, Teri has worked on almost 20 landfill cleanups and/or closures.  She has managed all phases of the process from early investigations, through remedial investigations and feasibility studies, landfill closure plans, closure design and permitting, construction management, and post-closure monitoring.  She is currently leading the team that is performing closure and groundwater remediation of B&L Landfill in Washington State—a wood waste landfill containing Asarco slag that is leaching arsenic at high concentrations into nearby wetlands.

In addition to landfill projects, other Resource Conservation and Recovery Act (RCRA) work includes technical and strategic integrations of the uplands and in-water portions of the RCRA cleanup of Boeing’s Plant 2 on the Duwamish Waterway, and a number of hazardous waste designation issues involving the more esoteric aspects of waste designation, including ignitability, reactivity, and derived-from wastes.

Teri also works in the aquatic environment, especially in urban ports.  She is one of the leading experts on the behavior of wood in the marine and freshwater environments, where she has performed numerous investigations, led the cleanup for the Wood Debris Group in Commencement Bay, established testing protocols in Washington and Alaska, and testified in court. Because wood is often a deleterious substance rather than a hazardous or toxic substance, Teri has also developed a solid working understanding of how various regulations, including the Clean Water Act, and various state laws deriving from the Clean Water Act can be used to manage cleanup decisions.
