Oregon Steel Mill
Stormwater treatment for a complex industrial site with discharge to an EPA Superfund river with strict regulatory oversight
This steel facility is 145 acres and operates as a scrap metal recycler and steel mill, discharging stormwater into the Willamette River. This river is an EPA Superfund Site, and as part of an agreement with the Oregon Department of Environmental Quality to implement an upland source control plan, the site owner agreed to install a treatment system to remove sediment, metals, and other contaminants. Clear Water designed and installed a permanent 3,600gpm chitosan enhanced sand filtration (CESF) system to treat turbidity, high pH, and other contaminants, and has been operating the system since installation. By installing a Clear Water system, the site owner has achieved a drastic 93% reduction in sediment, and addressed heavy metals. To date, the owner has been compliant with the Industrial Stormwater General Permit; discharging over 16 million gallons of treated effluent water below all benchmarks. Clear Water created and installed a custom online dashboard for the owner to monitor all parameters, generate trend lines, access reports, track weather, and interconnect with the Human-Machine Interface (HMI) through the Clear Water Client Portal on our website.
Gallons treatedThe CS-40 is a turnkey, containerized treatment system housed in a 40' CONEX box. Designed to manage high-flow conditions during heavy rain events, it integrates chemical injection, chemical storage, water quality monitoring, and pump controls into a single control unit.
Engineered for versatility and performance, the CS-40 is fully customizable to meet site-specific needs. Its robust design makes it ideal for demanding, high-volume applications across a wide range of industries.
Clear Water Services offers many adsorptive (and ion-exchange) mixed media filtration options and equipment to remove just about any contaminant from water or air. Our adsorptive multi-media filtration options treat water for heavy metals, hydrocarbons, VOCs, PFAS, PCBs, nutrients, microbes, pesticides/herbicides, and others.
Our team of experts can evaluate historical water characteristics, site constraints, and performance goals, and run bench/pilot tests to determine the best media for the job. Alternatively, we can simply supply the media and equipment per specification. Our equipment options include both gravity drain (passive) and pressurized (active) options, that can act as stand-alone treatment or as a final polishing step based on the application.
