  • The Washington State Department of Ecology trusted Haley & Aldrich to lead the remediation of a coastal site contaminated from a century of sawmill operations — the largest state-funded cleanup to date.
  • Coordinating with a team of scientists, engineers, archaeologists, and specialized subcontractors, we led remedial design and construction, creating a transformative plan that would not only clean up the site but also ensure long-term ecological and economic productivity.
  • We prepared plans and specifications in less than three weeks to facilitate construction in the same calendar year, and we completed the cleanup on time and within budget.
  • Our approach successfully balanced effective remediation with challenging Endangered Species Act requirements and the needs of local tribes and government agencies.
  • The revitalized area is now home to thriving businesses and ecological communities.
