For our technical guidance on the Riverside Property Cleanup, Aspect received a Best in State Silver Award for Social/Economic Sustainability at the American Council of Engineering Companies (ACEC) Washington 2013 Engineering Excellence Awards banquet on January 18.
The cleanup of the 90-acre Riverside property on the Snohomish River in Everett was conducted collaboratively through a public-private partnership between the City of Everett and Kimberly-Clark Worldwide - the Riverside Environmental Team (RET). With the RET relying on the technical analysis to drive the process, Aspect's deep understanding of MTCA regulatory requirements and strategic application of cleanup design and engineering steered the comprehensive cleanup of the former industrial property.
Aspect worked with the RET and Ecology to develop an efficient, focused approach and practical, cost effective engineered solutions that went beyond conventional industrial cleanup. Employing innovations including backfilling with available dredge sands and installing a subsurface drain system for use in groundwater treatment, Aspect oversaw a cleanup program of complete soil removal and active groundwater treatment that resulted in non-detect contaminant levels and six No Further Action (NFA) determinations for soil and groundwater.
Achieving unrestricted cleanup standards at the former Sawmill site preserved opportunities for a full range of future redevelopment options, not limited by capped contamination or deed restrictions.
The project was previously recognized with a 2011 Association of Washington Business (AWB) Environmental Excellence Award for Kimberly-Clark.
