A former pulp and paper mill in Everett, Washington, originally developed in the late 1800s, left behind significant legacy contamination in the soil and groundwater due to decades of heavy industrial activity, including petroleum storage and saw milling. After the facility closed, the site entered into an Agreed Order with the Washington State Department of Ecology to support long-term cleanup under the Model Toxics Control Act (MTCA). This marked the beginning of a multi-phase remediation effort aimed at transforming the site into a fully functional marine terminal for the Port of Everett.

The cleanup process involved extensive remedial investigations, feasibility studies, and the development of a formal Cleanup Action Plan. As construction progressed, the project faced numerous environmental complexities, including overlapping permits, evolving water quality benchmarks, discharge volume restrictions, and the presence of contaminants such as heavy metals and industrial chemicals. Proximity to Port Gardner Bay added further challenges, requiring innovative approaches to stormwater and wastewater management.

Over a five-year period, Clear Water Services provided critical treatment support through a series of customized water treatment systems. These systems were designed and adapted to handle a range of water sources, including dewatering flows, construction stormwater, and industrial runoff. Each deployment required careful planning around site logistics, treatment volumes, discharge limitations, and regulatory compliance. Clear Water worked closely with general contractors, environmental consultants, and agency stakeholders to ensure clean, compliant effluent throughout every phase of the site’s redevelopment.
