Windward Environmental

What Windward Environmental does

Windward Environmental LLC was a Seattle-based environmental science consulting firm founded in 2000 that specialized in producing defensible scientific data and unbiased technical analysis for complex environmental challenges. The firm served government agencies, industrial companies, and legal clients requiring evaluation of environmental contaminants, with a horizontal service portfolio spanning ecological risk assessments, human health risk assessments, metals toxicity modeling, sediment remediation and dredging support, environmental compliance and monitoring, habitat restoration, litigation support, and contaminated property redevelopment advisory.

The firm's core technical differentiators were proprietary scientific methodologies and data assets, including the Biotic Ligand Model for metals toxicity assessment in aquatic environments, a proprietary Metals Toxicity Database, and the Floating Percentile Model for statistical environmental data analysis. These tools reflected the firm's deep specialization in regulatory-grade scientific analysis and were developed and maintained by a small team of influential technical experts.

Windward operated as an employee-owned private LLC on a professional services model, delivering project-based consulting engagements custom-quoted to client scope, with go-to-market driven by direct relationships, technical reputation, and expert credibility rather than traditional marketing channels. The company served clients primarily across the Pacific Northwest and broader North America. On October 15, 2025, Windward was acquired by Barr Engineering Co., an employee-owned Minneapolis-based firm of nearly 1,200 team members, integrating Windward's specialized scientific capabilities into Barr's broader engineering and environmental services platform and ending Windward's 25-year run as an independent entity.
