  • Seattle

Ms. Kleven has more than 23 years of experience in complex site investigation and remediation utilizing innovative approaches. Ms. Kleven advises a diverse clientele in environmental matters with expertise in environmental chemistry, forensics and engineering. Projects have included chemical and materials manufacturing facilities, oil and gas processing plants, refineries, bulk fuels terminals, mining sites, research and technology facilities, liquid waste facilities, landfills (including areas reclaimed with leachable materials), and other waste management facilities. Ms. Kleven’s focus areas include historical site research, establishing baseline environmental conditions, planning and executing complex investigation and remediation projects, human health and ecological risk assessment, identifying alternative causes and responsible parties, employing environmental forensics to identify the source and timing of releases, site closure strategies, and regulatory compliance. Her expertise has been valuable as an advisor to clients managing environmental liabilities for a portfolio of legacy sites. She has served as member of confidential expert panels to evaluate and develop environmental investigation and remediation strategies for complex sites across the U.S.

For litigation projects, Ms. Kleven has identified and supported selection of testifying witnesses, and fully supported client and legal teams to develop and execute case strategies. Litigation projects have primarily focused on groundwater and surface water contamination and determination of the nature and extent of impact and the timing of release.

Ms. Kleven conducts environmental projects under many regulatory programs, including RCRA, CERCLA, MTCA, and other state and regional environmental and health programs. CERCLA projects include state Superfund sites with cost allocation for both upland and in-water/nearshore areas (e.g., rivers and waterways). Many sites are situated in complex hydrogeologic areas (e.g., fractured bedrock), residential areas, and ecologically sensitive areas. She has also supported large-scale redevelopment projects involving multiple parties and disciplines. Ms. Kleven routinely works at properties with operational challenges, such as sites that operate continuously and require minimal disturbance during investigation and remediation. Many of these sites are owned or operated by a third party.

Projects have involved impacts from a variety of contaminants such as petroleum hydrocarbons, PAHs, PCBs, pesticides, herbicides, insecticides, peroxide, cement kiln dust (CKD), resins, aluminum reduction waste, fly ash, scrubber slurry, solvents, ethanol, siloxanes, metals, and minerals/nutrients. A focus of her work has been evaluation of naturally occurring or area-wide metals and minerals/nutrients to develop baseline conditions.

Risk/Environmental Assessments

Prepared human health and environmental risk assessments for sites throughout the U.S. contaminated with hydrocarbons, chlorinated solvents, metals, PCBs, radionuclides, and minerals. The scope of these assessments included the preparation of exposure assessments, constituent characterizations, assisting in the development of toxicity assessments (for both carcinogenic and noncarcinogenic effects), and the derivation of risks, hazards, and/or health-based remediation goals for soil and groundwater. Select projects also included public involvement and litigation support. Successfully negotiated risk management solutions with regulatory agencies.

Conducted an endangerment assessment at an industrial research facility in Oregon for drainfield soils contaminated with depleted uranium. This endangerment assessment was completed for DEQ under the state’s Voluntary Cleanup Program. The scope of the endangerment assessment was negotiated with the agencies involved, DEQ and the Oregon State Health Division. Designed and implemented a field investigation, which included preparation of a complex SAP. The field investigation included radiation monitoring and the collection of over 500 soil, sludge, and wipe samples at the site for radionuclide analyses (e.g., gross alpha, gross beta, total uranium, isotopic uranium). The investigation and assessment resulted in a determination of no current or future significant risk to human health or the environment. Following completion of the endangerment assessment, DEQ issued a letter providing a “no further action” ruling for the site.

Due Diligence


Managed due diligence projects in Washington and Oregon for national clients seeking acquisitions or divestitures. These projects typically involved several businesses/properties and were completed on a fast-track schedule. Clients include insurance companies, real estate developers, chemical distributors, manufacturers, and others.

Managed a variety of due diligence projects for a client with multiple facilities in the western U.S. area. Performed Phase I/II ESAs and property screening.
