CWC 132: Aqueous solution with metals <br /> Site 2014 Quantity (lb) 2018 quantity (lb) <br /> LLNL 87,700 258,464 <br /> Primary waste generators: <br /> For LLNL <br /> 1.3 Tank Farm Aqueous Solution Treatment <br /> LLNL generated aqueous solution from its wastewater treatment operation at Building <br /> 695 located at the Decontamination and Waste Treatment Facility (DWTF). Aqueous <br /> waste generated by programmatic activities is sent to the DWTF for processing. <br /> The treatment process involved chemical preparation and rotary drum vacuum filtration <br /> without evaporation, which is a part of the wastewater treatment within the DWTF. The <br /> wastewater is treated to meet discharge limits and was sent to sewer. Wastewater <br /> treatment can vary from time to time based on mission-driven activities by programs that <br /> generate water requiring treatment. The increase seen in 2018 is due to an increase in <br /> programmatic work. <br /> September 1, 2019 SB 14 Report II-1 <br /> ESH-EFA-M-19-16592 <br />
