Avtex Fibers Superfund Site Feasibility Study by Exponent
The Avtex Fibers Superfund Site Feasibility Study by Exponent is underway in Front Royal, Virginia. Field crews sampled groundwater this summer, and in November, will be sampling the contents of several disposal ponds that hold "waste viscose," a soft, rubber-like by-product of rayon manufacturing that is releasing contaminants to groundwater. The Exponent team has submitted for agency approval the Laboratory Treatability and Analysis Plan, under which various innovative remedial strategies for dealing with the waste viscose will be evaluated. Those strategies include, among others, freezing and excavating it, electrically heating it to vaporize the contaminants, and even composting it with worms to convert it to useful fertilizer. The Feasibility Study is expected to take approximately 3 years from its inception last spring.
