Investigation Derived Waste
Concern for PRPs
Investigation Derived Waste (IDW) is the contaminated water, sediment, and soil, as well as PPE, materials, and solvents, produced during a site assessment or longer-term periodic monitoring or sampling study. Many regulatory bodies require this material to be captured and subjected to a disposal process that commonly entails collecting it in barrels for eventual shipment to a licensed waste facility, along with performing the requisite tracking and documentation. The costs for these processes can be high, and potentially responsible parties face concerns that additional costs resulting from the improper handling of IDW will eventually come back on them. In addition, it is prudent, and frequently required, to have the waste removed in a timely manner, and many companies are seeking to shrink their environmental footprint.
Reduction of Waste
By treating the liquid waste stream on site, ECT2 offers an economically attractive and more environmentally friendly approach that reduces PFAS waste volume to be hauled off site by orders of magnitude while producing treated water that can be released at the site, with PFAS concentrations that are below national health advisory levels or other regulatory standards for drinking water. For example, our process can take one million gallons of IDW wastewater and reduce that volume to one gallon of solid waste for disposal. Regardless of size or complexity, ECT2 has the expertise to deliver or manage each stage of the process, including system design and fabrication, water treatment and waste disposal.
Our approach to system fabrication is well-suited for the implementation of small truck- or trailer-mounted mobile units that can move from location to location to provide on-site treatment. These systems are designed to run in batch mode, rather than continuously, and are economical to operate whether treatment requirements are in the thousands or millions of gallons. Because many plumes contain contaminants such as petroleum products and VOCs (in addition to PFAS), we design our IDW water treatment systems to address combinations of contaminants, and our systems incorporate critical settling and pre-filtration components to address suspended solids in the water prior to treatment with our proprietary SORBIX resins.
Eielson Air Force Base near Fairbanks, Alaska experienced an unplanned release of 30,000 gallons of wastewater containing concentrated PFAS, and the Air Force Civil Engineer Center sought a system that could demonstrate the ability to rapidly address this immediate concern and potentially be applied to other PFAS releases or Investigation Derived Waste (IDW) waters containing PFAS.
This webinar will provide an overview of these developing standards, with a focus on the US, Europe and Australia.
