Independent, scientific research is a core part of Northwest Biosolids. The Research and Demonstration Committee funds new research through the University of Washington, Washington State University, University of British Columbia, Oregon State University, the University of Idaho and the University of Arizona. University representatives conduct research on biosolids management and its effects on the environment, working closely with biosolids managers and regulators to develop science-based regulations, guidelines and best management practices. The Committee works on special projects and monitors this research being conducted on biosolids issues and alerts members to new developments contained in research findings. Committee members visit potential application sites at the request of NW Biosolids members to advise on environmental, public health, community relations and operations questions.

Recent achievements of this Committee include:

  • Coordinated a risk analysis on trace organics from pharmaceuticals and personal care products, which was completed by the University of Washington and Kennedy/Jenks
  • Published NW Biosolids Research Summaries and Stories
  • Hosted webinars and workshops related to research projects, such as a webinar on the trace organics risk analysis
  • Given presentations and answered technical questions from members and the public

In the past, the Committee has:

  • Generated literature reviews on environmental, human health, and other topics related to biosolids management
  • Created regional biosolids demonstration sites, where the positive effects of biosolids as a fertilizer and soil conditioner can be seen
  • Formed Interest Groups to address research issues related to Forested Watersheds, Poplars, Rangeland, Soil Quality and Nitrogen
  • Developed fact sheets on research and demonstration projects
  • Co-sponsored an international forest symposium: The Forest Alternative: Principles and Practice of Residuals Use at the University of Washington
  • Organized Research Days discussing the state of biosolids research in the Pacific Northwest
  • Developed biosolids management guidelines for the Pacific Northwest
